gnu screen – changing the default escape command key to ALT-X?
It is possible to work around :escape command limitations using registers and :bindkey command. Just put this in .screenrc: # reset escape key to the default escape ^Aa # auxiliary register register S ^A # Alt + x produces ^A and acts as an escape key bindkey “^[x” process S ## Alt + space produces … Read more
When opening 2 files in emacs, how can I have them appear side-by-side?
Here’s a function that will change a pair of vertical windows to a pair of horizontal windows: (defun 2-windows-vertical-to-horizontal () (let ((buffers (mapcar ‘window-buffer (window-list)))) (when (= 2 (length buffers)) (delete-other-windows) (set-window-buffer (split-window-horizontally) (cadr buffers))))) To do this automatically on startup, add this function to emacs-startup-hook: (add-hook ’emacs-startup-hook ‘2-windows-vertical-to-horizontal)

Which keys are XF86Back and XF86Forward in EMACS?

wrong type argument: stringp, nil
You’ll need to provide more information to be sure. Try setting (setq debug-on-error t) which will give you a stack trace showing what function is complaining about the string being nil. My guess is that buffer-file-name is returning nil, and that’s where the problem lies (not all buffers have file names). Check out the debugging … Read more
.emacs global-set-key and calling interactive function with argument
Not minutes after asking the question I figured it out by copy+pasting code. However I have no clue how it works. (global-set-key (kbd “M-<up>”) (lambda () (interactive) (move-line -1)))
