elpa-transient 0.2.0.30.g4d44d08-2 (arm64 binary) in ubuntu jammy

 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.
