This is a pretty basic shortcut, but I use this constantly throughout the day! It’s helpful for working out of parent/child directories for design projects where I might want to have both levels accessible at the same time (i.e., reference photos for a design project and the related Adobe Illustrator files).
Thought it might be helpful to share! Let me know if you use anything similar or more efficient (I’m sure there’s an even better way to do this).
