hi Pascal, that's a point of view. From the other side, it can be considered that YOU've been distorted by 1980's computing interfaces.

hi Gabriel TEIXEIRA, all you need is to turn on the delete-selection-mode

• New Features in Emacs 23
http://xahlee.org/emacs/emacs23_features.html

quote:

Also, now you can hold down the Shift key then press arrows key to select text. To turn this off, put:

(setq shift-select-mode nil) ; “t” for true, “nil” for false

However, by default, pressing delete key will not delete selected text. If you want this, put:

(delete-selection-mode 1) ; make typing override text selection

i don't know if that is on in emacs 24, but maybe give it a try.

note that cua-mode also turns on the typing overwrite behavior, but is is not done by having delete-selection-mode, it implemented it's own.

also, if your selection is made by mouse, then it will automatically have delete selection behavior, even if delete-selection-mode is not on.

it short, the situation is a bit messy.

also, this problem happens to me too, that sometimes for some reason the delete selection behavior is gone. Quite annoying. When this happens, i call delete-selection-mode again to turn it back.
