Hi,
When using multicharacters keys, if a key definition entry is missing, emacs hangs and must be killed.
Example of an offending org-capture-templates definition:
(setq org-capture-templates
'(("t" "Todo" entry (file+headline "~/
somefile.org" "Tâches")
"* TODO %?\n %i\n" :clock-in t :clock-resume t)
("l" "Mail" entry (file+datetree "~/
somefile.org" "Divers")
"* EMAIL %?\n %i\n" :clock-in t :clock-resume t)
("fm" "some Menu - level 2")
("fmm" "template defintion - level 3 " entry (file+olp "~/
somefile.org" "Level 1" "level 2")
"* MEETING %?\n %i\n" :clock-in t :clock-resume t)
("fmt" "another template definition - level 3" entry (file+olp "~/
somefile.org" "Level 1" "level 2")
"*** TODO %?\n %i\n" :clock-in t :clock-resume t)))
The definition of the "f" key is missing.
In such case, org-mode should display a message and, do nothing or ignore
the offending tree.
