I carefully read those dos aain, and the entry for EM_GETREDONAME says it
returns data for "the last action". So it just won't let you inspect the
whole stack, quite expectedly as this is a _stack_ - you only can access the
top element of it.
So you are left with listening to the EN_UPDATE notifications, discarding
the ones that come from inner printable keystrokes. By "inner", I mean one
that doesn't start a sequence of printable keystrokes, since the normal
behaviour of the control is to group them into one action.
Yoou can use EN_CHANGE instead, but you need to ask the control to emit it.
EN_UPDATE is always sent on v2.0+ controls.
