This page is about libraries that highlight the current column of characters.
Library ColumnMarker lets you highlight and unhighlight any column. With no prefix argument, the commands
‘column-marker-3’ highlight the current column. The highlighting stays on that column until you highlight a different one or remove the highlighting.
‘toggle-highlight-column-when-idle’– Highlight the current column whenever Emacs is idle more than a certain number of seconds.
‘column-highlight-mode’– Continually highlight the current column, tracking the TextCursor as it moves. If you bind this to a key, you can also use it to briefly show the current column, by hitting the key twice.
‘flash-column-highlight’– Highlight the current column for
‘col-highlight-period’seconds. Another way to show the current column temporarily.
