Just for dummies like me, ...
I tried using key sequences last evening and spent a lot of time on it and it did seem to work, ... and like what could be so simple as a simple snippet routine.
I tried your suggestion to no avail, ... then the snippet start working intermittently. It took a while to realise this was a keyboard speed issue. It then took a while to find what was in plain sight the keyboard adjustment on the keyboard sequence interface.
I wondered why the apparent "default" required such fast typing and then I couldn't see any way of ensuring a convenient default for my typing speed in future keyboard sequence routines I create ?
