Moving in Emacs
The Emacs cursor just says where the next character will be printed, and such things like that, like in Vim, you can move it with the arrow keys, but this is a bad idea since you have to move your hands to do that.
Do this: put your hands on the keyboard in the most comfortable way possible, they don’t have to be on the home row, just comfortable position.
Very likely, one of your fingers is near the F key, other in the P key, and other near the B key, this are the keys you will use to move the cursor in Emacs. But since Emacs don’t have an insert mode “like vim” you have to use a modifier key. The most common are C (Control) and M (Meta)1
The movement keys have a meaning: F meanings forward (Next character), P previous (Previous line), B backward (Previous character) and N next (Next line)
You can see it this way2:
C-p : : C-b .... The cursor .... C-f : : C-n
This is hard to use at first. but keep using it for a while and you’ll love it more than “comfortable” Vim key bindings.
If moving character by character is too slow, you can try using the M-f and M-b to move word by word. M-p and M-n don’t do anything. So don’t try it.
Moving even faster
Sometimes you just have to go to the end or beginning of the line. Obviously Emacs supports this. with the C-a and C-e shortcuts.
C-a goes to the beginning of the line and C-e goes to the end of the line.
You can also go to the end or beginning of a sentence with Meta. M-e goes to the end of the sentence and M-a goes to the beginning
Most desktop keyboards have a Page Up and previous Page Down, this keys do work on Emacs, but they’re far from the keys we normally use. So we Emacs has it shortcut for it: C-v and M-v. C-v means next page and M-v previous page.
While editing configuration files. You probably want to go the end of the file and start typing, M-> will put the cursor on the last character of the file. And M-< will put the cursor in the first character of the file (This behaviour is the same as the Home and End key in a website for example. In Emacs, these keys just move the cursor to the end or beginning of the line (Like C-e and C-a)
There’s a weird keybinding: C-u (Universal argument) which gives a numeric value to the next keybinding you’ll use. For example. C-u 8 C-b will do C-b 8 times.
Open this file in Emacs and move across it (Try C-b, C-F- C-n, C-p, C-e, C-a, M-a, M-e…)
Meta key was a key present on very (very) old keyboards. Since the Meta key is missing on newer keyboards. We use left Alt instead. But if your keyboard (Sun Type 7 for example) has a meta key, you can use it instead of Alt. You can also use ESC instead of alt↩
While reading Emacs documentation, you’ll find a lot of M-* and C-*, M-f for example, means Meta + F, and C-f means Control + f↩
