How to set a keybinding to create and jump to the next line in emacs?
emacs next line
emacs delete line
emacs jump to line
emacs move to beginning of line
emacs show line numbers
emacs move-line up
I have the following code that attempts to create a new line and then jump to it. The idea is that
move-end-of-line will jump to the end of the current line, and
["C-m"] would act as return/enter. Yet executing this command gives the error: "wrong number of arguments". How do I fix this?
(global-set-key (kbd "C-.") 'new-line) (defun new-line () (interactive) (move-end-of-line) ["C-m"] )
I think you need to read the Emacs & elisp manuals: these questions are pretty easy to answer. Here's one way to do it.
(defun insert-line-after-line (&optional n) (interactive "p") (end-of-line 1) ;end of current line (open-line n) ;open n new lines (forward-line 1)) ;go to start of first of them
But seriously: Emacs has very extensive self-documentation, it is easy to find out how to do these things.
How to insert a new line and jump to it, in emacs?, You can make something akin to a keyboard macro like this. (global-set-key (kbd "<S-return>") "\C-e\C-m"). or indeed� See Variables, for how to set variables such as line-move-visual. Unlike C-n and C-p, most of the Emacs commands that work on lines work on logical lines. For instance, C-a (move-beginning-of-line) and C-e (move-end-of-line) respectively move to the beginning and end of the logical line.
An option is to record a macro and use that.
M-x kmacro-start-macro C-e C-m M-x kmacro-end-macro
If you don't care about the macro persisting, just run it:
But if you want it to persist you would save it:
M-x name-last-kbd-macro new-line M-x insert-kbd-macro new-line
and paste the output into your initialisation file (with your shortcut definition):
(global-set-key (kbd "C-.") 'new-line) (fset 'new-line [end return])
Moving Point - GNU Emacs Manual, 7.2 Changing the Location of Point The keyboard commands C-f , C-b , C-n , and C-p move point to the right, left, down, and up, respectively. so if you start in the middle of one line, you move to the middle of the next. nil value, C-n on the last line of a buffer creates an additional line at the end and moves down into it. Quit Emacs. Key bindings global-set-key Define a global key interactively. global-unset-key Unset a global key interactively. local-set-key Define a key binding to current major mode. local-unset-key Unset a key defined locally. Edit M-x delete-trailing-whitespace Delete trailing Whistespace and ^M characters or \r from Dos or Windows. M-x tabify
["C-m"] is like the way you specify a key for doing a key binding, but this is not the same as how you programmatically tell Emacs to insert a character into a document. You could use
(insert-char ?\^M) (see ref here), but that would result in a literal ^M character (try it; another way to do the same thing interactively is Ctrl-Q followed by Ctrl-M).
(insert "\n") seems to be what you're looking for.
Also, the reason you're getting the message "wrong number of arguments" is because
(move-end-of-line) requires an argument when called out of interactive context.
(move-end-of-line 1) works.
That said, possibly an easier way to achieve the result you're looking for is with the following setting:
(setq next-line-add-newlines t)
This will allow you to just do C-n at the end of the file and not worry about the distinction between moving and inserting.
Key Binding Commands, redefines C-x C-\ to move down a line. (global-set-key [M-mouse-1] 'mouse-set- point). redefines the first (leftmost) mouse� With the keybindings.json, it was always possible to redefine all the key bindings of VS Code, but it can be difficult to make a small tweak, especially around overloaded keys, such as Tab or Escape. To remove a specific key binding, add a -to the command and the rule will be a removal rule. Here is an example:
Setting up shortcut for goto-line : emacs, I am brand new to emacs and I am finding it tedious to goto lines using: I like to hook it to something that is quick but not sure how and how to make it quicker. C-a go to the beginning-of-line C-e go to the end-of-line C-n go to next-line C-p go to previous-line C-k kill the current line C-o open-line The following two bindings are CS210 specific: C-x C-g go to a specific line numbered x C-x C-w show (in the minibuffer ) the current line number
Keep moving to the end of lines, To be able to bind a function to a key we need to make it a command, so we need to use (global-set-key [remap move-beginning-of-line] #'my-move-beginning-of -line) and suggested key bindings (these bindings are made in setup-keys.el ). (end-of-line+ &optional N) Move cursor to end of current line or end of next� Altering the key bindings in Emacs should not, on the face of it, be a difficult task. But there’s a reason why the Emacs manual has dedicated 30-odd pages to describing, in great detail, all the subtleties and nuances of how to bind keys.
