How to redo in Emacs
Running through #DOOMEternal with all cheats on!SUBSCRIBE to DanQ8000 ⊳ A DANQ8000. Edit in workspace. This repl has no cover image. Emacs Lisp (Elisp) PHP Web Server. Enabling the:ui doom module makes emacs choppy and generally less responsive. I described it in this post, but the idea is that cursor movement and scrolling with C-u/d is very choppy, unresponsive, and slow. I tried disabling doom modules to track down the cause as I didn't experience the same issue with spacemacs, and interestingly it seems that disabling the doom module more or less solves. Completely new to Doom emacs and Vim mode do you have a good cheat sheet for commonly used commands? Really new, I knew my way with emacs but with evil mode I didn't even know how to erase a character haha. Emacs or EMACS (Editor MACroS) is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as “the extensible, customizable, self-documenting, real-time display editor”.
Emacs: Best Undo/Redo Mode, Short version: by undoing the undo. If you undo, and then do a non-editing command such as C-f , then the next undo will undo the undo, By default, redo in Emacs requires pressing C-g, then undo. However it's possible use Emacs built-in undo to implement a redo command too. The package undo-fu, uses Emacs built-in undo functionality to expose both undo and redo.
How do you 'redo' changes after 'undo' with Emacs?, Thus, to redo changes you have undone, type C-f or any other command that will harmlessly break the sequence of undoing, then type more undo commands. Note that the Emacs way of undo is very powerful in the following situation: edit A … undo A … edit B … undo B … redo A … With the new undo/redo system, the edit deletes the current redos, so when you undo A, there is no way to redo A later. There is, by using the normal emacs undo logic.
GNU Emacs Manual, The commentary at the outset of the undo-tree.el library describes two built-in methods to undo and redo: Emacs Undo/Redo Packages. There are a few packages for redo. Of the ones i've used are: redo.el by Kyle E Jones, 1997. redo+.el originally by Kyle, updated by S Irie, 2008. undo-tree.el by Toby Cubitt 2009. The redo.el works ok, but occasionally it corrupts your undo, meaning that you know there's more undo/redo but wasn't able to get to it.
Undo in Emacs
When the undo information for a buffer becomes too large, Emacs discards the oldest records from time to time (during garbage collection). You can specify how much undo information to keep by setting the variables undo-limit, undo-strong-limit, and undo-outer-limit. Their values are expressed in bytes.
Undo Commands Undo changes in Emacs with ‘C-/’, ‘C-x u’ or ` C-_ ’.
When the undo information for a buffer becomes too large, Emacs discards the oldest undo information from time to time (during garbage collection). You can specify how much undo information to keep by setting two variables: undo-limit and undo-strong-limit. Their values are expressed in units of bytes of space.
Emacs' undo-tree
Advanced undo/redo with undo-tree In emacs, by default C-/ runs the command undo, which does what you would expect and undoes your changes to the current buffer. However, there is a really great upgrade to this called undo-tree which records and visualises your undo history as a branching tree.
The `undo-tree-mode' provided by this package replaces Emacs' undo system with a system that treats undo history as what it is: a branching tree of changes. This simple idea allows the more intuitive behaviour of the standard undo/redo system to be combined with the power of never losing any history.
undo-tree 0.7.1 was published a short while ago, and with 15f2245 is now included with Doom. It fixes those regressions, former undo history corruption issues, and is finally working as it should. With that we'll be sticking to undo-tree. Hopefully the evil folks will reconsider as well.

emacsmirror/undo-fu: Undo helper with redo, Redo is two key-strokes. Holding a key to redo hits the first point of undo and immediately goes on to undoing those changes. Emacs’s undo system allows you to recover any past state of a buffer. While this can be useful, it complicates navigating the undo-history, especially in situations where a simple undo/redo commands are sufficient.

Exit Emacs
Basic Emacs Commands, (Note: C-x means to press the control key and while you are holding it down, press x. Other places use the notation ^X or ctrl-X.) You can use the arrow keys and also page up and page down to move the cursor. With SSH, you can have any number of windows. On a text terminal, suspend Emacs; on a graphical display, iconify (or “minimize”) the selected frame (suspend-frame). Killing Emacs means terminating the Emacs program. To do this, type C-x C-c (save-buffers-kill-terminal). A two-character key sequence is used to make it harder to type by accident.

On a text terminal, suspend Emacs; on a graphical display, iconify (or “minimize”) the To exit and kill Emacs, type C-x C-c (save-buffers-kill-emacs). A two-character key is used for this to make it harder to type by accident. This command first offers to save any modified file-visiting buffers. If you do not save them all, it asks for reconfirmation with yes before killing Emacs, since any changes not saved will be lost forever.
GNU Emacs Manual: Exiting, There are two commands for exiting Emacs because there are two kinds of exiting: suspending Emacs and killing Emacs. Suspending means Emacs waits until you exit the subshell. (The way to do that is probably with C-dor `exit', but it depends on which shell you use.) The only way on these systems to get back to the shell from which Emacs was run (to log out, for example) is to kill Emacs.
Emacs commands
Commands in emacs are either control characters (hold down the <Ctrl> key while typing another character) or are prefixed by one of a set of reserved characters: <Esc> or <Ctrl>-X.
Emacs Commands List C = Control M = Meta = Alt|Esc Basics C-x C-f 'find' file i.e. open/create a file in buffer C-x C-s save the file C-x C-w write the text to an alternate name C-x C-v find alternate file C-x i insert file at cursor position C-x b create/switch buffers C-x C-b show buffer list C-x k kill buffer C-z suspend emacs
Summary of essential emacs commands Use 'emacs foo' to create a file named foo, or to edit an existing file named 'foo'. You can do some work just by typing in the window once emacs comes to life. The backspace or delete key should do what you think it does.
Emacs save
Saving Files - Learning GNU Emacs, Second Edition [Book], correctly, it puts the message Wrote filename in the minibuffer. You can customize the value of save-some-buffers-default-predicate to control which buffers Emacs will ask about. C-x C-c, the key sequence to exit Emacs, invokes save-some-buffers and therefore asks the same questions. If you have changed a buffer but do not wish to save the changes, you should take some action to prevent it.
Save Commands, With a prefix argument, C-u C-x C-s , Emacs also marks the buffer to be backed up when the next save is done. See Backup. The command C-x s ( save-some- How Emacs saves the old version of your file. • Customize Save: Customizing the saving of files. • Interlocking: How Emacs protects against simultaneous editing of one file by two users. • Shadowing: Copying files to “shadows” automatically. • Time Stamps: Emacs can update time stamps on saved files.

Emacs undo multiple times
Is fast (repeated) undo possible in emacs?, Hold down Alt , type 2 0 0 , then press CTRL+x u . This gives an argument of 200 to the operation you are going to perform next (e.g. undo), so it applies that operation 200 times. By the way, CTRL+/ is also mapped to 'undo', if you would like to use fewer keystrokes. Hold down Alt, type 200, then press CTRL+xu. This gives an argument of 200 to the operation you are going to perform next (e.g. undo), so it applies that operation 200 times. By the way, CTRL+/is also mapped to 'undo', if you would like to use fewer keystrokes.

kill-buffer-hook, 19.4 Killing Buffers. If you continue an Emacs session for a while, you may accumulate a large number of buffers. You may then find it convenient to kill the On most operating systems, killing a buffer releases the memory Emacs used for the buffer back to the operating system so that other programs can use it. Here are some commands for killing buffers: C-x k buffer RET Kill buffer buffer (kill-buffer).
GNU Emacs Manual, C-x k ( kill-buffer ) kills one buffer, whose name you specify in the minibuffer. The default, used if you type just RET in the minibuffer, is to kill the current buffer. If you Use M-x kill-this-buffer. On my Emacs, it is mapped to s-k. Fewer keystrokes is better!

Emacs 28 undo-redo
[ANN] Undo-Fu 0.4 (with back-ported redo from Emacs 28) : emacs, As undo-fu was always meant to be a thin wrapper over Emacs built-in undo system, I've back-ported Emacs 28's undo-redo command into undo-fu , seeing as Emacs-28 won't be released for some time. By default, redo in Emacs requires pressing C-g, then undo. However it's possible use Emacs built-in undo to implement a redo command too. The package undo-fu, uses Emacs built-in undo functionality to expose both undo and redo.

(global-set-key (kbd Hold undo key, copy some part of the old buffer. Hold redo key until all operations have been redone. Then paste in the clipboard. While this is possible with emacs undo, it's made inconvenient because (as far as I know) there is no way to make redo stop at the point after undo began.

Introduction
The principles of Crime Prevention through Environmental Design (CPTED), a layered approach that emphasizes barrier-free observation, easy access control and clear boundary marking in addition to the same upkeep you’re probably already doing.Any site or building type can benefit from integrating the principles of CPTED. Familiarize yourself with the tenets of this common-sense design philosophy and learn how to spot red flags at your building.Credit: https://www.buildings.com/article-details/articleid/21405/title/who-s-watching-your-facility-
CPTED Basics
CPTED is a layered approach combining four principles: natural surveillance, natural access control, territorial reinforcement and maintenance. All four work together to create an environment that both makes potential criminals uncomfortable and enables occupants to notice anything out of place.Principle 1: Natural Surveillance
Natural surveillance is characterized by two complementary goals: minimizing ambush points and enabling the unobstructed observation of people with malevolent intent. Landscaping and lighting mistakes are the two biggest areas of neglect where this principle is concerned, followed by interruptions in lines of sight.Ideally, you should be able to see someone approaching from a considerable distance without any visual obstacles getting in the way, Ahrens says. “A good example is those car lots that look like Las Vegas, where you think ‘How much money are they spending on all that power?’ Well, if you were actually in the parking lot looking out to the foreground, you wouldn’t be able to see anything because where you are is so bright. However, the person in the background looking into the parking lot can see bright as day. The psychological component is ‘Who’s watching me while I’m in this parking lot?’ Thus we’re going to attract legitimate activity from people who want to buy a car. People who have illegitimate intent and are seeking to steal headlights or a car will be deterred because they would be observed or someone would call the police.”

Principle 2: Natural Access Control
This principle relies on using pathways, lighting and other means to direct traffic and define spaces for use. For example, instead of an open park where anyone can walk anywhere. Creating paths and use plantings to create borders.Natural access control is closely linked with natural surveillance, adds Audra Rigby, Principal of Certified Crime Prevention Consultants. Pathways and boundaries should be distinct enough to smoothly direct people from place to place but not obtrusive in a way that interferes with a clear line of sight. With landscaping, for example, Rigby recommends limiting small plantings or hedges to 2-2.5 feet and trimming tree canopies starting at 6 feet from the ground. “That allows for surveillance in and out of the building and the landscaping won’t block windows,” Rigby add
Principle 3: Territorial Reinforcement
Emacs Commands Cheat Sheet
Similar to the principle of natural access control, territorial reinforcement focuses on drawing clear lines between different properties and public areas vs. private ones by using both hard barriers (fences and walls) and soft barriers (plantings and lighting), as well as clues like artwork and entryways. “That eliminates all of the possible excuses people might have about why they’re not complying with the rules, such as why they’re parking in a certain area or why they’re on one side of the building,” Hushen explains.Principle 4: Maintenance
The importance of maintenance is supported by the broken window theory in which well-kept properties indicate to offenders that someone is watching the area, Rigby explains: “Maintaining the urban environment creates an atmosphere of order and lawfulness, which helps reduce the opportunity for crime on the property.”Conversely, rundown and dilapidated properties evoke the idea that no one is watching and the property is abandoned, which invites vandalism, littering and worse. Poor lighting has the same effect, Ahrens adds; good lighting is one of the best ways to deter crime, but if you cut too many corners or don’t maintain the lighting system, you could be asking for trouble.
