My Emacs skill is improved after 3 years
This is my note on useful commands/keybindings to memorize three years ago.
Most are obsolete because I'm more skillful now.
Basically I use fewer but more powerful plugins. I write Emacs lisp if there is no suitable plugin.
- Three years ago, column edit,
C-x r t yourstring RET (See "How to do select column then do editing in GNU Emacs ?"")
Now I use Evil
- Three years ago, save current position to register and jump to the position,
C-r SPC to save, C-j to jump (better-registers.el required)
- Three years ago, save frame configuration to register,
C-r f (better-registers.el required)
- Three year ago, (un)comment line,
M-; (qiang-comment-dwim-line required)
- Three years ago for visiting the next/previous error message after compiling,
"M-g M-n" or "M-g M-p"
I'm still using it.
- Three years ago, find-tag/pop-tag-mark
"M-." and "M-*"
- Three years ago, grep current work directory only or all sub-directories
Now grep in shell plus percol
- Three years ago, visit multiple tags table
hack tags-table-list directly might be simpler.
- Three years ago, set countdown timer
M-x org-timer-set-timer, C-c C-x ;
Now I don't push myself with the timer thing.
- Three years ago, mark subtree in org-mode
It was used to select the text to post to my blog.
Now I use org2nikola. The org-mark-subtree is hardcoded into org2nikola.
