select.column (Mod+Shift+F8) selects the same x range on a run of lines,
from two positions, two page points (Alt+drag), or by toggling column
mode where the arrow keys extend the block. Copy/Cut give one line per
row, Delete/Backspace remove only the block, character formatting and
Change Case apply per row, typing/paste replace the block. Any ordinary
caret move drops it. F8 keys now reach their shortcuts in the UI.
