# screen's help as tabs `this screen | keys | config | startup | about`;

# left/right switches, '/' filters within the visible tab, 'c' copies it,

# esc backs out (clearing an active filter first).

# Tab content lines are Spectre MARKUP strings (plain text pre-escaped), so

# the keys tab renders capsules; Get-PSMMHelpText flattens to plain text.
