Hi,
in el-search, the default key bindings are all of the form
control-shift-letter, like C-S (search-forward), C-R (search-backward),
C-A (go to the first match) etc.
Since these bindings are not available in a console, I want to provide
another configurable binding-scheme of the form prefix+letter, where
"prefix" is a prefix key the user can choose. In this case, I want to
equip the commands with a transient map so that the prefix has to be
given only the first time one of the commands is invoked. For example,
if the prefix is meta-s e,
meta-s e s s a
should invoke a forward search, then go to the next match, and then to
the first.
The transient map is the same for all prefixes, but in the shift-letter
case, it's wrong to use the transient map; it would be surprising when
C-S followed by r would search backward instead of stopping the search
and invoking the self-insert-command.
My question is: is there a way I'm not seeing to achieve this without
defining two sets of commands (one set establishing the transient map,
another without)?
FWIW, my idea was consulting `this-command-keys', but due to bug#27470,
I can't use it in my case.
Any ideas?
Thanks,
Michael.
