:l1. I believe that you mean a "type ahead" buffer, not "look ahead". In fact, Companion doesn't use such a buffer at all; the enormous speed of the screen display routine makes this unnecessary. As you have noticed, Companion will never miss a keystroke.<be>

:3. The numerical comparison of textbuff er sizes for programs which operateusing different algorithms is sometimesmisleading. In addition to the18,000 character text buffer, Companionuses a separate 1,200 byte linelength buff er to keep track of linelengths, and wil will (in the rare case that atext users more than 1,200 screenlines) logically synthesize additionalline lengths. TI-Writer may put theline lengths (and maybe a flag witheach one) into the text buffer. Also,Companion's left margin declarationallows the program to avoid storingspaces to represent the left margin ofeach line separately. For TI-Writerthis may amount to at least 4,000 charactersin a large (say, 500 line) text.Additionally, TI-Writer may placevarious extraneous flags in the textbuffer; I don't know.<br>4. An option: I think that it is worthmentioning that "G" is easy toremember since it stands for "graphics,"and that "H'' " stands for"horizontal tab" (not "T," as onemight reasonably expect).<br>5. The space bar should not really beconsidered a cursor motion key. Also,all of the cursor motion keys (in fact,all keystrokes period) repeat automatically,and the repetition graduallyaccelerates.
