just to be clear, beyond quitting layout right ? you want to close all opened documents but keep layout open ?
then yeah. it’s one by one
cmd-w on mac will always close a window while cmd-q will quit the app. even in Layout and sketchup.
But you’re right, weirdly enough, most daily softwares on my PC will do the same with ctrl-w (firefox, explorer…) but not Layout and Sketchup. I get why in SU, each file has its own instance, but I agree with you, layout needs the standard shortcut + a small X to close the tabs. like a browser.
Command-Option-W does close all LayOut documents without quitting LayOut, on Mac. There isn’t even a keyboard shortcut for closing one LayOut document on Windows, though of course you could add one.
Even if it would rarely be useful to close everything and leave LayOut open, having a Close All would be reasonable.
Here are the options in Chrome, that could be applied to any tabbed application, including LayOut on Windows:
Anyway, I’m sure @trent will know if this is already logged as a feature request.
