A nice summary of presentation options in org-mode/Emacs by Sacha Chua.
This is useful. Though it is in the orgmode manual, I’ve never read it thoroughly.
In Emacs, the command replace-string will replace all occurrences in the buffer. If you want Emacs to ask you each time it is about to replace a string, you need to use the so-called “query replace.” This can be invoked by M-%.
textlint is a program to analyze and check written text for style problems (think of “The Elements of Style”). It has binaries for Linux, Windows and Mac OS. It has interfaces for Emacs, VIM and other editors.
Seems useful for writing LaTeX documents in orgmode.
Useful when you lost the current line in Emacs. Happens very often to me.
Command set-input-method sets the current input method in Emacs. There is a TeX input method for entering many TeX symbols (says \alpha, \le, \leftarrow) as Unicode characters. There is also a Vietnamese-telex input method for entering Vietnamese characters. Very useful. Now I don’t need Vietkey when I work in Emacs.
To toggle (turn on/off) input method, use C-\. When it is off, you can use the keyboard as usual.
