One wrinkle is that the custom shortcut
obviously works in qt applications
also works in text boxes in Firefox (gtk3) and Google Chrome (gtk3)
also works in Leafpad (gtk2)
but
doesn't work in Mousepad (gtk3) and Gedit (gtk3) and LibreOffice Writer with libreoffice-gtk3 instead of with libreoffice-kde5.

In the lower half, you can set up window matching rules, in case you wish to send the keyboard to an application/window that is not the "currently active window".

There is the "Help" button on the lower left corner you can use to get more information on this.

When you explain it that way it makes sense to me. I did read the "Help" even before asking but ...

Could you also explain the purpose of the lower window? To me it looks like all the work is done in the upper window

Exactly, thank you!

I assume you mean the "send keyboard input" action in "Custom Shortcuts"?

If so, here is an example how to use it:

shift+f:i:r:s:t:space:shift+l:a:s:t:enter:
shift+a:d:d:r:e:s:s:enter:
shift+s:p:e:c:i:a:l:space:c:h:a:r:space:shift+7:enter

(I put it on multiple lines for better readability, but you don't have to)

produces:

First Last
Address
Special char &

Quite some time ago, I came across a thread at KFN dealing with setting up shortcuts to type predefined snippets.

I can't find that thread now

In particular, suppose I often want to type a multiline address into qt or gtk applications how do I do that?

Person's name
Apt. number
Building Name
Street
State
ZIP code

(For snippets that are one-liners, I use Rofi.)
