I'd like to create a macro that puts my cursor right into the Finder/Spotlight field outlined in blue in the screenshot below, so that I can search for all files whose name contains whatever text string I choose to enter. I.e., I want it to call up this particular search template. I can use Select to access Finder->Find, but I don't know if KM has a built-in command that lets me go deeper.
If you're doing this manually from within Finder, you need to click the "+" button to right of Save (at the window's RHS; here it's already been clicked, so it displays as a "-"). That opens the advanced search options you see below. Within the latter, you need to change the left-most option to "Name", and then change the following option to "contains".
I did find, among Peter Lewis's set of example macros, one called "Finder Find by Name", but that doesn't work on my system (and, in addition, likely doesn't incorporate the "Contains" modifier).
