Idea: "Find" option for display runtime

[kasemir]

User suggested adding a "find" option to locate items on a display.

Note that this is already available in the display builder web runtime, https://github.com/ornl-epics/dbwr, where the web browser supports "Ctrl-F", then enter some text, and labels or buttons with that text will be highlighted, typically supporting "Ctrl-G" to go to the next match on the screen.

As an implementation idea, the display representation (JFX) would have to listen to key presses, locate a matching widget on the display, and could then "focus" on it. That would for example highlight a button. Pressing "Enter" would then activate that button since it has the focus.
As a downside, the "focus" tends to be subtle, so an added highlight of some sort might be necessary.
