I notice in Geany 1.27 (Mint 18.1 repo) it doesn't save search terms.
Which is fine, especially between sessions.
In Geany, I take it there's also no "clear recent documents?" (you can
set the # of listed recent docs in the config file).
I don't know if it's designed never to save search or "find & replace"
history, or if I edited some file and don't remember it.
There definitely aren't any menu or prefs for "don't save search
history" - or such.
There are no settings in any Geany files to control any of this, that I
see. It's OK - I'm just surprised. Most apps save some history and you
have to find a way to delete it, if need to.
If I edited something in Geany's files to not save search history and
forgot what I did, I'd like to see if there's a way to apply it to
Mint's text editor.
In Linux Mint, the default text editor is XED. I could easily change it
to another editor - even Geany, that doesn't save search history or can
clear it.
XED has no preferences to not save history; no way to clear it.
XED's Search & "replace with" terms are stored in a binary file -
"user." The only way to delete those entries is using the tool,
dconf-editor, which isn't that convenient on a regular basis.
