I do not know the details of the source code well enough to say, but evidently pico and nano handle screen output very differently, so that one makes speakup say the char under the cursor when the cursor moves, and the other does not. But you have to distinguish between cursor tracking and speaking the current text as the cursor moves. Perhaps it has to do with how an application chooses to show you the cursor. If it shows you the cursor by brightening the char the cursor is on, perhaps by rewriting that char to the screen, that should be easy to catch. The situation in DOS was relatively easy compared to Linux. DOS has system calls that tell you where the cursor is and what char is there. What I did was for every key press to record the current cursor position befpre [assomg tje cjar tp tje suste,. tjem waiting an arbitrary time and checking the position again. If it moved from its original position, then I did one of three things: (1) if it moved only one position, I pronounce the char at the new location; (2) if it moved horizontally more than one position, I read enough chars from the screen to isolate a 'word' and pronounce that word; and (3) if it moved vertically, I read the line to which it has moved. That was a good plan, but it meant capturing the key stroke before the system gets it, as well as capturing data sent to the screen, and coordinating the two. I think there is room for improvement in the way speakup speaks the cursor movements, since at present the way it does it varies from one application to another, and it shouldn't do that. I am not an emacs user like Kirk is, but I am told that emacs behaves even more friendly than nano does in that respect. Hey Kirk, are you reading this? How about switching to pico for a day or two so you can see how a weak application works? <smile> Chuck Visit me at http://www.mhonline.net/~chuckh "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -- Benjamin Franklin, 1759.
