No, it's not.

You can send those key events by typing Alt Z C, Alt Z S, and Alt Z A
(they are listed in /lib/keyboard) if you really need them.

Control and Shift are already handled properly when you type a control
or uppercase character, so the only time you really need them is to
type Alt or to do fancy mouse clicks with keyboard modifiers.

Plan 9 handles Alt for itself, so that you can type Unicode characters
into every program, not just ones that have been specially coded.
