Options - Keyboard Shortcuts

How to assign keyboard shortcuts

To assign a keyboard shortcut to a function, select an item and press key combination you like.

By default, shortcut keys without modifier keys (Ctrl, Shift, and Alt key) are not allowed. Check the checkbox if you want it.

Remove a keyboard shortcut

Select the item you remove shortcut and press Esc key.

Default keys of * marked items can be set to pass-through by Shift+Esc

For example, "Ctrl + W" is assigned to "Close Tab" by default of QTTabBar.
Even after you have disabled this function or assigned other key combination, Explore does not receive "Ctrl + W". By setting "Close Tab" to pass-through, QTTabBar will pass it to Explorer.
This option is for processing those keys by other application like mouse gesture processor.
