Hi
one alternative subject could be "because it is Friday"...
I am using org-mode and ess regularly, and I use quite a few keyboard
shortcuts, but each time I read about a new one, I am wondering: why
the heck these specific (default!) keyboard shortcuts?
I am not asking why keyboard sequence, but e.g. why "export" in org is
C-c e and why tangle is C-c C-v t, and so on.
In other words: I am trying to *understand* why C-c and not C-o,
because I have tremendous problems to remember the shortcuts - if I
would know that there is s tree structure, where each following key
narrows it down to further *thematically linked* commands, it would
make it easier to learn these.
Any insight into this? Or is there a emacs function which returns a
random keyboard shortcut for a given function (some emacs shortcuts
really seem to be that way...).
Thanks,
Rainer

Obviously the keys ran out pretty quick. Now only few shortcuts are reserved for user space and plugins, the most notable of which is the `C-c` prefix. That's why most custom modes such as org-mode and ESS bind to shortcuts with `C-c` prefix: there's a convention that Emacs core will not use `C-c`. A nice way of remembering shortcuts only when you need them is to call commands by name with `M-x`. After a while, when you note that you're using one particular command a lot, you'll want to learn the shortcut for it. There's one package that might be of good use to you: `smex'. It uses ido completion for `M-x`. You can install it from MELPA/Marmelade. It binds automatically to `M-x` when you install, although I recommend: (global-set-key "\C-t" 'smex) As an example, say you want to tangle. Here's what you do: C-t tang Now you see a bunch of rectangle commands mixed into the bunch. You can filter them out by noting that tangle commands have `org` in their name. C-SPC org C-SPC Now there's only 7 candidates left and you can select the one you want with C-m either by cycling with C-s or continuing to type part of name. `smex` logs the commands you use most. For them it usually takes less than 2-3 characters from the name to be recognized. E.g. if you use `org-babel-tangle` a lot, you can usually call it with C-t bab C-m. Finally note that no shortcuts are set in stone. You can customize all of them if you want to do so. For instance, and probably a lot of people will disagree, it doesn't make sense for me to have `previous-line' on C-p. So I swap C-p and C-h: (keyboard-translate ?\C-h ?\C-p) (keyboard-translate ?\C-p ?\C-h) Oleh On Fri, Dec 6, 2013 at 10:02 AM, Rainer M Krug <Rainer@krugs.de> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hi > > one alternative subject could be "because it is Friday"... > > I am using org-mode and ess regularly, and I use quite a few keyboard > shortcuts, but each time I read about a new one, I am wondering: why > the heck these specific (default!) keyboard shortcuts? > > I am not asking why keyboard sequence, but e.g. why "export" in org is > C-c e and why tangle is C-c C-v t, and so on. > > In other words: I am trying to *understand* why C-c and not C-o, > because I have tremendous problems to remember the shortcuts - if I > would know that there is s tree structure, where each following key > narrows it down to further *thematically linked* commands, it would > make it easier to learn these. > > Any insight into this?

I can't speak for the original developers however my take on this one is as follows: C-b (for beginning) is used for "back" C-s (for start) is used for "search", C-f (find) was "forward". C-a becomes beginning-of-line by virtue of being the beginning of the alphabet.

To be clear, C-c followed by another modified key (C-x, for example) is reserved for major modes. C-c followed by a regular letter (e.g. C-c x) is reserved for use by the user, and should not be used by major modes. Tyler ^ permalink raw reply [flat|nested] 8+ messages in thread
