What I am after is the ability to trigger quickfilter with default criteria from a button and concurrently select the filter string so that it can be edited immediately without the need for a mouse click. Something like a FOCUS option perhaps? Set QUICKFILTER *.exe FOCUS
On related matters, it appears that a specific Set QUICKFILTER xxx command operates as a toggle by default when repeated. For example, starting with no quickfilter panel showing, executing Set QUICKFILTER *.exe pops up the quickfilter panel and applies the supplied filter:
Executing the same command a second time clears the panel and removes the filter, effectively acting as a toggle. This is not an issue but it's not what I expected. Executing a different quick filter - e.g. Set QUICKFILTER *.dll replaces the original filter criteria and leaves the quickfilter panel open.
