tmux push/pull panes
Moving panes between tmux sessions is something that makes tmux a very flexible and powerful tool. I don't need this feature very often, but it comes in clutch when you need it.

tmux zoom
https://youtu.be/Rn6mOarCQ-Y Zooming into the current split in tmux is a valuable tool to give yourself some screen real estate. These days I am almost always presenting, streaming, or pairing up with a co-worker over a video call. Since I am always sharing my screen I am generally zoomed in to a level that is just a bit uncomfortable, so anytime I make a split it is really uncomfortable, being able to zoom into the split I am focused on is a big help, and also help anyone watching follow where

tmux new-window
https://youtu.be/YRPZBv-iYyE New window as it sounds makes new windows in tmux. Windows are kind of like tabs. They are another screen within your sessions that you can name and make new panes in.

tmux resize-panes
https://youtu.be/hpFYE2LU7xc Resizing panes in tmux can be quite difficult in default tmux, I use a set of keybingings to help resize panes in the rare occasions that I do need just a bit more space. I set the keybinding to the same as my split navigation bindings but shifted. They are very vim like (h,j,k,l). Most often when I need to resize panes I just grab the edge of the pane with my mouse. Yes the mouse, its not that often that I actually need to change the size of a pane. tmux-nav-2021 fo

How I navigate tmux in 2021
In 2021 I changed the way I navigate between tmux sessions big time. Now I can create, kill, switch with ease, and generally keep work separated into logical groups.

Keyboard Driven VSCode
Throw that mouse Away its time to setup some keyboard shortcuts. These sortcuts were the baseline for switching from tmux/vim to vscode. Most folks posts I was able to find gave great tips on replacing vim, but very few have focused on the hackability of tmux. tmux allows me to rapidly fire up a workspace, create new windows and splits. Then When I switch tasks I can leave that workspace open and and jump right back in later exactly where I left off. There is nothing quite like it. The shortcuts
