The website of Texstudio advertises block selection or multiple cursor functionality, but I could not figure out which key combination to use for this feature reading their horribly cryptic user-manual.
I am familiar with how text selection with multiple cursors works in Sublime Text, for instance. Those key combinations don't work here.
Would someone be kind enough to please tell me how to do this in Texstudio? Thanks.
The key combination for block selection is Shift+Ctrl+Alt (See Sect. 2.8.1 in Manual)
Press them all together and simultaneously move the mouse or cursors to select the text.
Alternatively, Ctrl+Alt can be used to place multiple cursors without selecting, even in the same line or in non adjacent lines.
Without the mouse, you can use Ctrl+Alt and Up/Down arrows keys to place multicursors.
And for special use cases, there is Edit/Searching/Select All Matches, to create multi cursors after searching text with the search bar.
Edit/Selection/Select All Occurernces is like Edit/Searching/Select All Matches, but for the current word (the one where the cursor is currently placed) rather than the search.
In TeXstudio 3.0.0, there are new commands Edit/Selection/Also Select Next|Prev Occurrence to create multiple cursors to the next|prev occurrence of the current word.
