Often in rapid typing I make many little typing errors like may occur in this very sentence I'm typing. I'll deliberatly wait until I'm done before going back to correct the errors, and deliberatly make a copy so you can see the original and the final version of this. There, 3 errors corrected, all by string search instead of pointing device. [Addenda, a fourth found on second reading just before dispatching this message, also located by search, fine-adjusted by incremental-cursor, see below, and corrected by auto-insert default EMACS mode.] [Further addenda, a fifth found and corrected.] The point I'm making is that whereas mouse is advocated as useful for text editing (now called "word processing"), in fact most of the time simple typos can be found and fixed by backwards string search easier than by any kind of location-specific pointing device such as mouse or cursor. Thus your advocating of a mouse in text editing is a red herring. Furthermore, having used the string search to get in the vicinity of the error, typically at the start or end of the seach string depending on which editor is being used (in EMACS backwards search puts you at start, but pressing ctrl-S can put you immediately at end), you still need to step to the point of corrction in the middle of the erroneous string, and for that I would think incremental cursor controls would be much easier to use than a mouse because you can step forward or backward N characters by pressing the appropriate cursor-step key N times whereas with a mouse it's very hard to quickly determine you're at exactly the correct spot instead of off by one. Thus for simple correction of typos, the most common thing done other than straight typing, it seems you'll need incremental left/right cursor commands in any case, even if you have a mouse, while the mouse won't be used because it's dominated by searching and stepping. [Addenda in second paragraph (third if you count both clones of first paragraph separately) typed&inserted at this time, just before adding CC:WORKS and dispatching. RMAIL is nice.] [Further addenda in that same paragraph added now, on third reading, after adding CC:WORKS, just before dispatching.]
