Description of the Issue

I wanted to disable the CTRL-W shortcut as I switch between nano and notepad++ and I was constantly closing files in notepad++ on accident. So I went into the shortcut mapper, and right clicked the Close shortcut and cleared it. But now when I press CTRL+W it inserts the special character ETB?

Steps To Reproduce

1. Click Settings, Shortcut Mapper
2. Right click on the Close CTRL-W shortcut and click Clear
3. Press CTRL-W with a document open

Current Behavior

ETB is inserted into document when a key mapping is not even defined for CTRL-W

Expected Behavior

ETB should not be inserted, nothing should happen as the shortcut is cleared. The input should just be ignored by notepad++
