transient-display-buffer-action in Other Options.
You may have noticed that the bindings for some of the common commands
do not have the prefix
C-x and that furthermore some of these commands
are grayed out while others are not. That unfortunately is a bit
confusing if the section of common commands is not shown permanently,
making the following explanation necessary.
The purpose of usually hiding that section but showing it after the user pressed the respective prefix key is to conserve space and not overwhelm users with too much noise, while allowing the user to quickly list common bindings on demand.
That however should not keep us from using the best possible key
bindings. The bindings that do use a prefix do so to avoid wasting
too many non-prefix bindings, keeping them available for use in
individual transients. The bindings that do not use a prefix and that
are not grayed out are very important bindings that are always
available, even when invoking the "common command key prefix" or any
other transient-specific prefix. The non-prefix keys that are grayed
out however, are not available when any incomplete prefix key sequence
is active. They do not use the "common command key prefix" because it
is likely that users want to invoke them several times in a row and
M-p M-p M-p is much more convenient than
C-x M-p C-x M-p C-x M-p.
You may also have noticed that the "Set" command is bound to
while Magit-Popup used to bind
C-c C-c instead. I have seen several
users praise the latter binding (sic), so I did not change it
willy-nilly. The reason that I changed it is that using different
prefix keys for different common commands, would have made the
temporary display of the common commands even more confusing,
i.e. after pressing
C-c all the
C-x ... bindings would be grayed out.
Using a single prefix for common commands key means that all other
potential prefix keys can be used for transient-specific commands
without the section of common commands also popping up.
particular is a prefix that I want (and already do) use for Magit, and
also using that for a common command would prevent me from doing so.
(Also see the next question.)
qnot quit popups anymore?
I agree that
q is a good binding for commands that quit something.
This includes quitting whatever transient is currently active, but it
also includes quitting whatever it is that some specific transient is
controlling. The transient
magit-blame for example binds
q to the
command that turns
So I had to decide if
q should quit the active transient (like
Magit-Popup used to) or whether
C-g should do that instead, so that
could be bound in individual transient to whatever commands make sense
for them. Because all other letters are already reserved for use by
individual transients, I have decided to no longer make an exception
If you want to get
q’s old binding back then you can do so. Doing
that is a bit more complicated than changing a single key binding, so
I have implemented a function,
transient-bind-q-to-quit that makes the
necessary changes. See its doc-string for more information.
