If you liked Sacha Chua's post on micro-habits that I wrote about yesterday, be sure to check out her video on the same subject. In it, she discusses various packages for switching windows and for jumping around in a buffer or even multiple buffers.
She also discusses how she leverages the
key-chord package to invoke her window switching and buffer navigation. You don't have to worry about trying to remember her configuration because it's available online in an excellent literate programming Org file. Watch the video and get any specifics you need from her configuration file.
The video is just over eight and a half minutes so it should be easy to fit a viewing into your schedule. As always with Chua, your time will be well spent.
