- I was discussing block operations with a good friend of mine who is a
- professor in the Computer Science department of the University of South
- Florida.
-
- We discussed the two systems of handling text blocks. The big-cursor
- system, and the one where the block is independant of the cursor.
-
- The block=big-cursor method seems the most natural to me, and one of the
- reasons I like it is that the cursor commands are heterogenious, where
- the same commands that work on text work on blocks just the same, and
- another reason I like it is that it takes a lot fewer total keypresses to
- deal with than the other method and requires less memorization.
-
- My friend the professor, though, says that heterogenious commands can
- have their disadvantages. If the block operations are independant of
- cursor and text operations, then things like accidental Ctrl-A become an
- irritation, rather than a danger.
-
- So, I suggest a compromize. Let's not treat the block as a big cursor,
- but find a way to reduce the work involved. The commands should be
- simplified. Are you up to the challenge?
-
- It's not going to be easy. The keypresses (the ones new to to the
- standard) will have to be moved to places in the keyboard where they are
- easy to deal with. Ctrl-( and Ctrl-( on the keypad are too far away.
- Change them to Ctrl-B and Ctrl-E. Hide block shouldn't be Shift-Ctrl-A,
- because of the number of keys involved; change it to something like
- Ctrl-H (one of the things I despize about this method of handling blocks
- is that a selected block that I don't want selected is VERY annoying to
- see, and I especially hate it when there's no command to hide the block).
-
- Now, if we exchanged the Ctrl-shift-A for the Ctrl-A, then all this work
- would be saved, but insisting on having Ctrl-A as select-document is
- forcing us to do this or end up with a standard with massive holes in
- it. Who's going to sit and look at they keyboard to figure out how to
- make block-operations more efficient? Someone's got to do it.
-
- Now, the professor and I agree that shift-backspace is a BIG NO-NO! For
- those of you who didn't see it before, I'll give an example. You're
- typing this:
- "Some of the things in this standard are EXTREMENLY"...
- You're holding down the shift key to type in the string of caps, and you
- realize your mistake and instinctively hit backspace. BAM! Your line is
- gone. As I'm sure you can see, this is bad. It happens to me frequently
- in Atari Works, and I dare say that one of you could come up with a
- solution short of removing shoft-backspace from the standard. If
- shift-backspace were to delete a word, it wouldn't be a whole lot better,
- because one would instinctively hit the backspace key 3 times in the
- above example, thereby deleting 3 words, which isn't very nice either.
