Hi! Who knows is there the way tohide annotate lines I draw in viewport using hotkey?
Hi,
Initially, there’s no hotkey for that, but you can make one! There’s a lot of YT tutorials on that topic.
But what you can do for sure is to hold your left mouse button on annotate icon, it will show your the other annotation tools as well, where, among other things, you’ll find so-called “Annotate Eraser” (or just press Shift Spacebar, 8 as a hotkey for that), then, you’ll be able to erase your annonate.

UPD: Yes, you can assign a shortcut to it, when have opened an additional Annotate tools menu, hover on “Annotate Eraser*” and click RMB, that’ll open a pop-up menu (see screenshot below) where you are able to assign a shortcut to that tool, just click on “Assign Shortcut” and press your button you would like to call for that function.

UPD 2: Unfortunately, it will work just a in the first case, thus you would need to manually remove your lines.
Cheers,
Sergey
