Well, it is almost ideal 😉 :
In hialgo_settings.ini, there is a section
TOGGLE_HIALGO = F10
TOGGLE_RESOLUTION_KEY = 04 ; 04 is the middle mouse button. See below about how to specify any button or key.
And somewhat below (from line 33) there are even instructions on how to encode different keys (including, as in your example, PGUP and PGDN in line 41).
I do not remember whether it is possible to add more lines to hialgo_settings.ini, to configure other commands you are interested in.
You may try to figure it out: open HiAlgoBoost.dll in some HEX editor, then try searching there strings like F10 or TOGGLE (but you have to use UTF-8 format, not ASCII). And the success is not guaranteed.
