When you press a hotkey, HotkeyNet is normally the only program that sees the pressed key. If you want the keystroke to have its normal effect in addition to triggering the hotkey, you have to say so like this:

If you write PassThrough anywhere in a hotkey defnition, it always executes immediately when you press the hotkey before any other part of the hotkey is executed.

This means PassThrough is not subject to If-conditions.

The program is designed this way because PassThrough is executed by the keyboard hook, and the hook needs to run as fast as possible, without slowing down to examine If-conditions.

If you want to put PassThrough inside an If-block, use SendFocusWin instead as shown in this example.
