Add ability to clear shortcut

[Lewis8379]

Preflight Checklist

• I have fully read the README and it did not solve the problem.
• I have searched all open and closed issues for the same bug report without success.

EverythingToolbar Version

1.0.3.0

Windows Version

Windows 10 Enterprise 10.0.19045

Steps to reproduce

1. Open the search window, click the 3 dots, click "preferences", click "change shortcut", enter a shortcut, and save.
2. Decide you don't want a shortcut
3. Do step 1 to bring up the window
4. Try to clear the window, by using backspace, escape, highlighting the text and deleting it, etc. The shortcut will become backspace, escape, etc

Expected Behavior

Pressing escape or back should clear the field and remove the shortcut - who would use escape or backspace as a shortcut anyway?

Actual Behavior

It is impossible to clear the shortcut

Thank you for the suggestion. In the next release it will be possible to clear the shortcut by pressing Esc.
