Pulled, thanks a lot Arnaldo!
Btw., incidentally I noticed an UI detail: in the 'perf report' and 'perf top'
TUI, PageUp does not move the cursor to the topmost line, it stays at whatever
partial page position it is.
I think it would be better to behave here like good editors do: PageUp in the
first partial page moves to the first line (like 'Home') - and PageDown on the
last page of output moves to the last line (like 'End').
Btw., even popular TUI editors get this wrong sometimes:
- 'nano' (joe clone, popular mail editor) gets this right in both directions.
- 'vim' behaves this way on PageDown, but not on PageUp. Nor does it recognize
Home/End, only Ctrl-Home/End works.
- 'emacs (e3 package) gets the PageUp/PageDown behavior right, but no Home/End
key combo works (and exiting the editor is painful as well ;-)
Thanks,
Ingo
