With mouse scroll up, the position of the cursor moves as the window gets updated. =20 > And when you say "point moves across the window", do you mean that > point moves with the text or that the text moves, but point stays at > the same screen coordinates? Depending on how you scroll, it could be > one or the other. If the point stays at same screen coordinates, or moves with the text; the point still moves from its original position (originally positioned after parenthesis of interest). Have noticed that when I scroll, the=20 cursor point always shown up in the window. =20 > Next, what do you mean by "highlighting get recomputed as the point > moves across the window"? What happens with highlighting as you > "scroll" that you don't like? Let there be a long function, and you put the cursor at the point following the last parenthesis. With "show-paren-style" being expression, the functi= on=20 code get highlighted. Suppose I want to go to the beginning of the functio= n which resides outside the window pane. The highlighting is disabled as I g= o to the beginning of the function. > And finally, what would you like to happen instead in this case? I would like the possibility of freezing the highlighting (not only when us= ing 'expression put also for 'parenthesis). Currently I loose all the parenthe= sis or expression highlighting when I need to move through the code. =20
