You probably know that if you highlight text with cursor, and push Ctrl+B, you can get
\textbf{highlighted text} instead of what was before:
highlighted text I would like to create a keyboard shortcut similarly for the following:
\colorbox{pink}{highlighted text} I am using TeXStudio.
I think the closest thing you can do is to set up a macro (Macros>Edit Macros...).
You can either select one of several keyboard shortcuts (here Ctrl+M+C),
or an abbreviation that, when you type it like a regular command, shows up in the auto-completion window marked with '(Usertag)'.
Highlighted text will be inserted at the marker for curser position %|.
