change alt to control for shortcuts

[tessus]

I changed the modifier key from Alt to Control, which makes it possible to use it on macOS.

The Deselect all shortcut has also been changed from Control+A to Control+D.

fixes #4829

@tessus Thanks you for doing this! ❤️

Since it's easier for you to test (since you have a Mac) could you please confirm that all these shortcuts work on both Safari and Chrome?

IIRC there was some potential conflict e.g. with Ctrl+O being the browser's "open" as well but TBH I'm fuzzy on the details and might be misremembering -- so the shortest path is to just test and make sure.

I believe FF behaves similarly to Chrome so testing on Safari & Chrome should be sufficient

[tessus]

Yep, it works on Firefox, Chrome, and Safari.

Hmm, I just saw that I cannot commit the generated file. I did that only, because it wsa in the source tree. Shall I remove it from my PR?

Yes, please.

I don't think we've ever had anyone submit a malicious patch, but webpacked files are difficult to review. Letting the bots run webpack is safer than doing manual review.

[tessus]

Done.

I'm slightly confused why you committed my changes again. Now they are no longer gpg signed. Anyway, not that important, just curious.

@tessus I was just rebasing them on top of the lastest commit in main, that's all

[tessus]

I see, thanks for the info. I usually only rebase in a branch when there are conflicts, which is why I didn't understand why a rebase was done.

Notes: Fixed broken keyboard shortcuts on desktop Safari.
