I used (concat (symbol-name major-mode) "-map") to get
current keymap, but it failed for LaTeX mode. Are there
other methode to get current keymap.
If I enter a buffer, do `M-x latex-mode',
then M-: (concat (symbol-name major-mode) "-map")
it returns "latex-mode-map". What did you want?
That's the name of a symbol whose value is the latex mode keymap. If you want
the keymap itself, then you want this:
(symbol-value ; Value of
(intern ; Symbol whose name is
(concat (symbol-name major-mode) "-map")))
However, (current-local-map) gives you the same thing, and it works regardless
of the name of the symbol.
(eq (symbol-value
(intern
(concat (symbol-name major-mode) "-map")))
(current-local-map))
=> t
