For bug reports, provide the steps to reproduce and if possible a minimal demo of the problem.
When double/triple clicking and dragging, the cursor does not select by word/paragraph and instead ignores it and selects by letter.
Thanks for reporting the issue with double-click and drag selection in ONLYOFFICE, and for sharing those videos!
We’re aware of this bug where double-clicking and dragging doesn’t select by word as expected (like in Notepad). I’m used to word selection with double-click too!
Good news: triple-clicking does work to select an entire paragraph. Unfortunately, we don’t have a timeline for fixing the double-click issue yet, but it’s logged as a bug.
