For what it's worth, the 'mintty' terminal used by default for Git for Windows as well as MSYS and Cygwin has another approach to the whole problem. Its rather flippantly named 'Flip Screen' context menu command with Alt+F12 or Ctrl+Shift+S shortcut lets users temporarily look at the alternate screen buffer while the main screen buffer is active, and vice versa. If 'less' is invoked without the -X option, it will switch to the alternate screen, where mousewheel scrolling works by sending cursor up/down keycodes. While in 'less', you can temporarily flip to the main screen to look up something in the shell session there or copy something for searching in 'less'. While looking at the main screen, the mousewheel will scroll the scrollback buffer. Keyboard input that's sent to 'less' will flip back to the alternate screen. Quitting 'less' switches back to the main screen, so the 'less' output disappears and you're back in the shell session with the command that invoked 'less' as the last thing shown. But again, the 'Flip Screen' command or shortcuts can be used to temporarily look at or copy from the alternate screen, which will contain the last page displayed by 'less'. (The alternate screen does not have a scrollback buffer.) The 'Flip Screen' feature of course also works with other alternate-screen applications, for example editors. Apparently the Mac terminal has such a feature as well: https://support.apple.com/en-ie/guide/terminal/trmld1f46097/mac (Full disclosure: I originally made mintty, from PuTTY.) Kind regards, Andy
