One way to make your use of Vim more efficient is to make use of viewports (splits). This article from linux.com explains just about everything about how to used the viewports in vim. However there is one thing it does not mention, and this is how to changed the width of a vertical viewport. Here’s how.
Ctrl+w > widens the viewport (Press Ctrl+w and then “>”)
Ctrl+w < narrows the viewport (Press Ctrl+w and then “<”)
As usual with vim you can also use modfiered to chage how much you widen/narrow the view port. For example, to widen it by a 10 instead of 1:
Ctrl+w 10> widens viewport by 10
The number can be replaced with any value and also applies to the narrow viewport command.
