Adding a file here, 'display-issue.cxx'.
If compiled as is (on linux/flwm), no caret appears, even if you use
TAB to shift focus to/from the button.
But if you comment out the (A) line, this causes the display to take
focus, allowing the caret to appear, and it remains even if you use
tab to shift focus from it.
Also: when the caret is visible, keynav can't be used to move it;
only mouse clicks and selections can manipulate it.
