I noticed that when I edit multiple files the only way to cycle between open files is to do the following:

ALT + v
s "Focus Statusbar" or f "Go to file" or CTRL + P
#naigate to file with arrow keys 
enter 

An alternative to reduce the number of keystrokes could be

ALT + ` (also the ~ key)

This could either cycle directly between all open files or show the open file window.
I would be happy to take a look at adding this if this is a desired feature (and it isn't already present)
