Writing a command inside it has no effects (I tried with
/usr/bin/xterm which normally starts an xterm, and with
/usr/bin/touch /home/choroba/ABCD, but the file wasn't created).
I think it's the search box of PCManFM file manager.
- The text in it is used to locate a file by file name.
The first matched file will be selected automatically, so that when you press ENTER, the selected file will be opened/issued, and the search box will be closed.
If no file matched (like your case), then no file will be selected, press ENTER will just close the search box.
The file name matching logic seems to be:
"file name".startsWith (
"text in search box")
- After a short time with no key input, this search box will be closed.
I saw a search box in Caja file manager too, but search box will not shown when typing in the desktop (MATE Desktop).
