For the *VAST majority* of my searches, I don't know the folder where
the desired file is. Either I'm researching a problem with an unfamiliar
program or I know that very similar file names exist in several folders.
Therefore, I wish to set "Look in folder: to "File System".
How?
"MATE Search Tool" takes the "G" in GUI seriously ;/
"Look in folder:" is the label of a drop-down menu.
"File System" is one of the items in that list of labels:
"richard" (/home/richard)
"Desktop" (/home/richard/Desktop)
"File System" (/)
-then a list of the labels of other partitions *mounted/unmounted*
"Other" (a Thunar-like display for choosing a directory)
I have not discovered a pattern in how the default for "Look in folder:"
is determined.
I generally wish to force that entry to be "File System".
TIA
