As Sigil's devs might guess, I'm looking forward to able to switch focus between panels (windows) via the keyboard… but there's one thing I do want to raise.
I'm pretty sure Sigil originally assigned F2 to regex rename, and Ctrl+F2 overtype rename. And I recall swapping them to make F2 conform to IBM's SAA CUA de-facto standard… overtype rename. See
https://www.mobileread.com/forums/sh...63&postcount=4.
I also recall 'losing' F2 when when it was assigned to the Preferences external-editor. When that happened, I cleared the Launch external xhtml editor shortcut assignment and gave F2 back to overtype rename. I don't need a shortcut for the external xhtml editor. I'm more likely to use an external editor on an image or use Page View on the opf, so Book Browsers Open suits me better.
