Is your feature request related to a problem? Please describe.
I imagine my buffer will get large at some point and while I've seen some workarounds for this like naming blocks and using search I wonder if there is a faster way for me.

Describe the solution you'd like
I'd like to be able to bookmark a block or a line within a block so I can toggle back and forth between two blocks that might not be close to each other.
