I've been seeing this issue for at least a couple of months - it may have been around longer.
Proclaim 3.0.0.0048 on macOS 11.0.1
While setting up our presentation, I frequently use the "Reuse Item" menu option.
Bringing up this dialogue presents me with a menu that contains a text entry field. Typically I will start typing the name of a frequently used slide. Sometimes I mis-type and need to start over.
The workflow: Add Item > Reuse Item > click inside "Find" text entry field > begin typing > if I make a typo, or decide to search for something different, then "Command + A" to select all. > nothing happens.
Given this has been a text selection feature of macOS for decades, and is basically a muscle memory thing for us Mac users, not having Select All work by Command + A is a major flaw.
Can someone please look into this and hopefully fix it so this field responds to Mac keyboard shortcuts the way Mac users are accustomed to?
Thanks,
Benjamin
