5181 - KeyMap Settings - Add Keyboard Shortcut doesn't report all conflicts

Yesterday I had to reconfigure my Keymap again due to ENTER key not working for Inline Rename.

I noticed that while setting up the keys, sometimes the Add Keyboard Shortcut wouldn't report some of the conflicts.

For example,
I wanted to assign CTRL+W to Select Word.

I used the DescribeKey plugin to tell me what was bound to CTRL+W and it reported:
Assigned to



But when I went to the IDE Settings->Keymap and did Add Keyboard Shortcut on the Select Word at Caret action, it only reported:
Assigned to GUI Designer
