We can close a Tool Window with Shift+Esc. What is the shortcut to hide a Tool Window? I have tried Ctrl+M, Ctrl+H to no avail.
For example, when the Locals window is open, I can close it with Shift+Esc but not hide it.
Closing a tool window preserves its state and actually works like hiding. Maybe you want to assign a shortcut to the Window.AutoHide command (also available in the main Window menu).
