How do I find out what modes are currently running in the current Emacs buffer?
589
To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
The standard default value is fundamental-mode . If the default value is nil , then whenever Emacs creates a new buffer via a command such as C-x b ( switch-to-buffer ), the new buffer is put in the major mode of the previously current buffer.
You can explicitly select a new major mode by using an M-x command. Take the name of the mode and add -mode to get the name of the command to select that mode (e.g., M-x lisp-mode enters Lisp mode).
A minor mode is an optional editing mode that alters the behavior of Emacs in some well-defined way. Unlike major modes, any number of minor modes can be in effect at any time. Some minor modes are buffer-local, and can be turned on (enabled) in certain buffers and off (disabled) in others.
You can see the major mode and all the minor modes enabled for the selected buffer with:
C-hm
or
M-x describe-mode RET
The mode line also displays information about the major mode, and usually some minor modes.
I also recommend you run the tutorial with C-ht, which will teach you a great many useful things.
