emacs - emacs word replace not working for me?

Question

Following this thread;

How to replace a word in Emacs?

to replace a word, when I issue M-@ it selects the word but when I begin typing the new text the selection disappears and the new text is inserted in front of, instead of replacing, the original word. Why?

Answer 1

M-@ を発行すると、選択のみが行われます。単語を削除するか、削除選択モードを有効にする必要があります。
