@danperks if all my other software has worked fine with ctrl + a and ctrl + z for 5+ years with PowerToys, it seems unfair to say that PowerToys is the “cause” of them not working in Cursor.
Can Cursor ensure the keys work, like all other software I’ve used on this PC for the last 5+ years please? 
BTW, there are other cases of standard keyboard usage not working in Cursor e.g. @harrisyu 's tab (!) is broken here.
