The usual SHIFT + CMD + / (slash) shortcut does not open the “Search” line in the “Help” part of the application menu.
This key combination usually works perfectly in other programmes. It allows to quickly find and use functions by typing the functions’ first few letters. A big white arrow appears next to the highlighted function. Push ENTER and it’s done.
Customising shortcut keys is not possible because the “search” function does not exist.
Any advise OTHER than telling me to customize shortcuts for every single function I want would be welcome.
