禁用瞬态标记模式

Question

In my .emacs file, I have

(setq transient-mark-mode nil)

and yet transient-mark-mode is activated when I start up Emacs. Calling transient-mark-mode gives the message "transient-mark-mode disabled", but Control - Space still starts highlighting a region.

Is there a way to turn this off?

You might have cua-mode enabled as well which has similar region highlighting to transient-mark-mode . To test this just Mx cua-mode (to toggle it on/off) and see if it disables the highlighting.

From Ch f cua-mode help:

CUA mode manages Transient Mark mode internally. Trying to disable Transient Mark mode while CUA mode is enabled does not work; if you only want to highlight the region when it is selected using a shifted movement key, set `cua-highlight-region-shift-only'.
