Hi, I don't know how other people quits the message display but I do feel unhappy since the first day I use vim and have no good work around unless having a big screen (so that most messages could fit in my screen)... The more frustrating thing is: if I continuously scroll down in the 'more-prompt' mode, the 'more-prompt' will eventually quits the display and the message are disappeared forever, so I must be careful NOT to press any key when the last line of message are shown. What I expect is: press "Enter" or "space" will always do scroll ONLY, and do never quit the message display, this is consistent with the Unix "less" command. If you just eat the 'q' after the message display, it will work if you want to just quit all message, but when you want to view the last lines of the message, the 'more-prompt' is still inconsistent since it will change into "Press Enter or type command to continue" on the last line. So I think a better way is to change the code for the 'less' mode, (in Vim document, it is called 'more-prompt'), the 'more-prompt' should always require 'q' 'ESC' to exit, even if the last line of text are shown. And there should be an option to turn the 'more-prompt' always on. i.e. All message will show 'more-prompt' regardless of the message 'lines'. To conclude: 1. an option to "always show" the 'more-prompt' 2. 'more-prompt' will never fall into "Press Enter or type command to continue" state even if on the last line, so we always require 'q' or ESC to quit the 'more-prompt'. this is consistent with the Unix 'less' command. -- Sincerely, Pan, Shi Zhu. ext: 2606
