Switch between layouts quickly – In Layout mode, switch between layouts by pressing a keyboard shortcut and typing the layout’s name. As you type, a list of matching layouts appears. See Layout creation and navigation (Windows) and Layout creation and navigation (macOS).
This one is really nice to have. It hasn't been included in the menu's yet? At least it on mac OS.
I already have a feature request for it. I'd like to be able to open the full list of layouts, perhaps six ahead and six behind, with the current layout selected. In my work I often want to switch between several layouts which are grouped together and it's easy to forget whether I should be going forward or back.
The shortcut to use the layout number was appealing. Press ESC, type a layout number. Wow! A pity the layout number dialog they discuss isn't included in the Mac OS window chrome.
Tried that out, but did not work - then, I realized that I had that shortcut already globally assigned by another app (-:
Yes, Malcolm, the same in Windows. Nice little feature when in layout mode though.
