|Press and hold <CTRL> then <1>||YES|
|Press <CTRL> release it then press <1>||NO
When using 1 – 3 combination of modifier, holding down or click at the same time, eg: <CTRL><SHIFT>, this is considered as hotkeys / shortcut keys. When type 1 by 1 will be considered as character of strings (the same like when you type something) which usually use in hotsrings. but there is no other way to use modifier and key in hotstrings.
“Hotstrings are mostly abbreviation expanders, designed to expand typed strings, not to create multi-key hotkey (a feature asked some times already, search “combo hotkey”).”
