Allow symbol:slider, make single sliders not macro in this syntax

[SainoNamkho]

Currently keys like cursor_up does not work if configured with the long syntax.

I feel like this is a lot of code for an edge case. What do you think of leaving the bug in place with a mention in the doc ?

Maybe I mixed up too much problems in a single patch because one cannot be fixed without the others.😂

I have a specific use case, what do you think of it?
I make every swipe in cardinal directions, which have no function yet, a cursor move. So I can swipe to move cursor from any position. And I hide the icons, because otherwise there will be arrows everywhere on the keyboard. Sounds like a well-founded need?

In favor of that, I need:

• cursor moves with customized symbols, which are macros now, work as sliders.
• the symbols persist while modified.
• in order to implement the previous item, calls to withSymbol might pass key font symbols. I choose to check if the first character is in PUA. This is inconsistent with other typed based overload solutions, but there isn't a good way to do this.

I'm pleased if there would be other ways for this need.😊
