Ctrl + Backspace 
In many programs, this key combination deletes the word to the left of the cursor. This does not work in some programs/entry fields and instead adds a character like ?, e.g. in Windows Editor (notepad.exe). Ctrl + Backspace functions correctly with this option.

Ctrl + C in text fields 
If you want to copy the text in an entry field, you have to mark it first. If this option is active and no text is marked, press Ctrl + C or Ctrl + Insert to copy the complete text of the entry field to the clipboard.

Ctrl + C for other controls 
Is a button or checkbox is active (has the focus), the text in the button or other control element is copied to the clipboard.
