Exact steps to reproduce the issue

nnn 4.9 tmux 3.4 bat 0.24.0 less 643

If the previewed file exceeds the window height, it will get stuck when scrolling to the end of the file, and then will display：Waiting for data... (^X or interrupt to abort). I found a similar issue: https://github.com/sharkdp/bat/issues/1055 , also may be related to pager less.

Update: This defect also appears in the preview directory function, so the bug should be related to the pager less.

I used ov instead of less and it works fine now.

https://github.com/noborus/ov

change preview-tui:

  "NNN_PAGER=${NNN_PAGER:-less -P?n -R -C}"                # pager options
to
  "NNN_PAGER=${NNN_PAGER:-ov}"                # pager options
