Hmm.. IIUC there're 3 modes of annotation view: percent, period and
sample, right? The existing 't' hotkey seems to toggle between
percent and period. And you added 'e' for sample and percent, right?
I'm not sure percent by sample and percent by period are both needed.
If so, I think it's better to add a hotkey to toggle between percent
and value (both for period and sample). And existing key should
toggle between sample and period.
If percent by sample is not meaningful, I'd rather make the hotkey to
circulate through percent, period and sample.
Thanks,
Namhyung

I agree on it. It seems to be better than two hot key !
I'll change this patch based on your comment.
Arnaldo, what do you think about this ?
On annotate TUI browser
hot key: 't'
circulating: "Percent" -> "Sample" -> "Period" -> "Percent" -> ...
Thanks,
Taeung
