On opening PhpStorm's Terminal Tool Window, I would expect to be able to run commands like Ctrl + Tab to switch terminal tabs, or Cmd + 1 to open the Project Tool Window, but my keyboard is stuck inside the Terminal.
Is there a way to release the keyboard from the Terminal so that I can return to regular commands? (Without using Option + F12 to hide the Terminal Tool Window.)
Switching between Terminal tabs can be done using the same shortcut as Editor tabs: Alt+Left/Right on Windows using Default keymap (on Mac it would be Cmd + Shift + [ and Cmd + Shift + ] (or whatever you have got there for Main Menu | Window | Editor Tabs | Select Next/Previous Tab
-- you can verify/change it in your Preferences | Keymap
)).
Project View tool window shortcut (Alt+1 on Windows or Cmd+1 on Mac) does not work indeed if used in Terminal.. but shortcuts for Favorites or Structure tool windows still work just fine.
Therefore I may suggest to jump to Structure via Alt+7 (Cmd+7 on Mac) first and then just use Esc to get into Editor). P.S. See if recording macro with such sequence will work for you (you can assign custom shortcut to it).
