precedence of keymaps

precedence of keymaps

[Andreas Politz]

Hi,

some time ago I wrote a little global minor mode,
which defines a couple of keys for resizing, moving windows etc.
The idea is, that every key which is not bound in this mode
is bound to "exit-mode, restuff event".

The problem is that some modes shadow my modes map. Scanning
through the manual it seems that the precedence of keymaps
is determined by some mode list. My intuition tells me
that the last activated mode should always take precedence.

Do I have to always reorder said mode list or is there a better
way to ensure that some keymap is always on top, when it is
activated ?

humm? i don't quite understand what u mean ... exit-mode and restuff
event?

you are aware that local keymaps override global ones, right?

... perhaps someone who knows better can answer.

i am also interested in a mechanism so that user defined keys has
absolute priority everywhere.

i haven't really read thru the whole chapter on keymaps
http://xahlee.org/elisp/Keymaps.html
but i'll do so now...

See

  (info "(elisp) Searching Keymaps")

As you have found out the minor mode maps competes with each other.

Like the repeat `mode', where you press 'y' and it repeats the last command,
but every other key works normally.
When a keymap has a (t . some-command) cons, every key not mapped calls
some-command. If this some-command turns of the keymap (the mode) and
pushes the event, which was not mapped, back in the event loop, it's like
auto-shut-down (mode wise), might call it a mini-mode.
