This post covers the first two sections from the "Default Operations" section of my init.
- Moving the Cursor and Screen
- Make/kill/move windows frames buffers
- Projectile, Helm and Smex
- Clip board (kill ring)
- PDF tools and command line history
Emacs is old school. You're either new to it - which means you wouldn't be here unless it was your type of thing - or you know what you're looking for. In either case, go to the side bar of this page and click on the 'Emacs' tag. Then read the posts y date from oldest to newest.
In the last emacs post I covered lines 1115 - 1195. This post covers lines 1195 - 1366. I include the lines for anyone that wants to patch together the entire init from start to finish. The lines won't always match up because I take stuff out when I'm in the init.
Moving The Cursor and Screen
I added some spaces between these sections. Saving point, and adjusting the scroll behaviour are standard Emacs defaults you want to set. Copy paste these defaults and that's fine. Mwim is great for changing up C-a, C-e, which are end of sentence and beginning of sentence. What I use to move around the most are C-p, C-n, C-a, and C-e. I also use M-< and M->, which are bound to beginning of page and end of page, though in the code below they are bound to

Make/Kill/Move Frames, Windows, and Buffers
Delete-all-other-buffers and new-frame-scratch-buffer are two functions I use a lot! I like to have a lot of frames open and cycle through them with tab, and you always get a lot of buffers open. My fix is to kill all the frames either with C-x 0, or with a kill frames command, then I open and jump to a scratch buffer and kill all the buffers but the one I'm. It's easier than a restart when you want to clear out your last session and start new. I rarely rotate windows, but I do use frame commands now and then. The switch window package is a little annoying. C-x-o jumps you from one window to another window unless you have more than two open, then switch window gives you a letter to choose. Without switch window you cycle through the open windows, maybe better but you sometimes forget where you are.
