Hi I'm on Linux and Emacs version is 26.3.
I would like to expand or collapse a block by mouse click, instead of moving the cursor to the header and press tab.
I actually have a windows computer does so, but do not work on my Linux one. I’ve tried to copy relevant files, however doesn’t work.
I also googled, but to be honest, cannot find where to start.
So if anyone can help? Thanks a lot!!
