Calling functions with optional arguments from the mini-buffer

Grant — Sat, 12 Jan 2013 21:51:28 +0000

Surely one of the first things VIers want to know as do the rest of us is how to move forward N characters (or backward or whatever) from the mini-buffer in EMACS. Here is how it is done, using the universal argument. So to move forward 100 chars:

C:u 100, C:f

ADDENDUM:01/13/13

Thanks FUCO for providing a better solution:

There’s also a faster way. Just hold down control key (or meta key, by default the binding is on both) and type the number, then execute the command or invoke minibuffer with M-x

So, C-2 C-0 C-f will move you 20 characters. It’s neat because you don’t have to release control, you just hit the rest of the keys in sequence.

Making jess-mode v1.2 work on Emacs 24

Grant — Wed, 10 Oct 2012 15:49:37 +0000

If you try running jess-mode with Emacs 24 you get an error about “shared-lisp-mode-map” and jess-mode doesn’t work. Someone already described the fix here, and it works!

Here is a patch.
