Taking inspiration from prefix keys and prefix arguments, Transient
implements a similar abstraction involving a prefix command, infix
arguments and suffix commands. We could call this abstraction a
"transient command", but because it always involves at least two
commands (a prefix and a suffix) we prefer to call it just a
"transient".
.
When the user calls a transient prefix command, then a transient
(temporary) keymap is activated, which binds the transient's infix
and suffix commands, and functions that control the transient state
are added to `pre-command-hook' and `post-command-hook'. The
available suffix and infix commands and their state are shown in
the echo area until the transient is exited by invoking a suffix
command.
.
Calling an infix command causes its value to be changed, possibly
by reading a new value in the minibuffer.
.
Calling a suffix command usually causes the transient to be exited
but suffix commands can also be configured to not exit the
transient state.
