(or, how Stewart is obviously very easily pleased …)
At work, I use emacs over an ssh connection in a Gnome terminal window. For months, I’ve complained that it wouldn’t respond to mouse clicks, and thus cursor movement was tiresome.
So today, on going back to a particularly large project file, I wondered if anything could be done. Googling for “emacs xterm mouse”, I discovered xterm-mouse-mode. It does what it says on the tin; gives you basic mouse control in an xterm. I’m happy now. Almost too happy, in fact.
I also found out about flyspell-mode today, an on-the-fly spelling checker for XEmacs. It does the equivalent of the little wiggly red line under misspelt words in Word, except not quite so in-your-face. Neato-mosquito.
