584 - Search results hotkey issue

[Dreamer]

I can't always reproduce this bug, with any files, so I'll try to write specific conditions:

- in FC open the folder with the program that is running
- open search dialog (path of that program should be in the Folders field)
- search the containing text (existing)
- press Enter
- errors tab should be opened
- the first file in the results list is focused
- press F3 to view the file
- it works good
- close the viewer
- now press F4 to edit it
= it doesn't work
- click the file with left mouse button
- press F4 again
= it works good now

I can reproduce it also with the mp3 and video files, so try this:

- enter the folder with the few mp3 or video files
- open one file (it must be running)
- search the containing text, e.g. "feat" for mp3 files
- press Enter
- the first file in the results list is focused
- press F3 to view the file
- it works good
- close the viewer
- now press F4 to edit it
= it doesn't work
- click the file with left mouse button
- press F4 again
= it works good now

External editor should be set for specific file types, e.g. *.mp3 - audio editor.
