As a new PL8 user I am a bit horrified about the lack of user-re-assignable keyboard shortcuts.
I have found a partial workround which may help some people, and I couldn’t find mention of it on these pages, so here it is.
I have a Logitech MX keyboard, and it comes with software that allows you to assign hot keys uniquely for each application. Any key assignment you make has no effect outside of the specified application.
I suspect that the software works with many other Logitech keyboards, and perhaps other keyboard manufacturers do something similar.
Worth a look if, like me, you were struggling with the shortcuts.
Cheers
