@@ -61,6 +61,8 @@ The following options output metadata about the commandline state:
- ``-P`` or ``--paging-mode`` evaluates to true if the commandline is showing pager contents, such as tab completions
- ``--paging-full-mode`` evaluates to true if the commandline is showing pager contents, such as tab completions and all lines are shown (no "<n> more rows" message)
- ``--is-valid`` returns true when the commandline is syntactically valid and complete. If it is, it would be executed when the ``execute`` bind function is called. If the commandline is incomplete, it returns 2, if it is erroneus, it returns 1.
