Mouse scrolling in vim scrolls terminal window

Question

I am just getting started using Vim and came across :set mouse=a which I've found really useful for navigating a file, however for some reason when I try and scroll now it scrolls the whole terminal window and not just the vim window.

Then I scroll up and can see the terminal outside Vim

Any ideas on how to fix this? I've tried resetting mouse= and exiting and re entering vim.

Answer 1

The problem was that I had accidentally disabled Allow Mouse Reporting in error.

Checking Menu > View > Allow Mouse Reporting or Cmd + R has fixed it!

Answer 2

I think the cheap answer to your question is that you should be navigating through files in vim using motion commands, Ctrl + d, etc. It might seem slow at first, but it really becomes more natural down the line.

That said, if you are on Mac and using Terminal, you might need to hold the Fn to temporarily disable mouse support. (Check this out for reference: OS X Terminal Mouse Support

Also, you can always try MacVim, which supports mouse scrolling out of the box.

If neither of those solutions work for you, some more information would be helpful for troubleshooting, e.g., your operating system, recent changes to your vimrc, etc.
