Right, and I think we better find other hotkey and make Ctrl+Z work like with other tools, i.e. suspend: [acme@zoo linux]$ mutt [1]+ Stopped mutt [acme@zoo linux]$ vim [2]+ Stopped vim [acme@zoo linux]$ The perf TUI should work like that as well... Ideas? We already have: h/?/F1 Show this window UP/DOWN/PGUP PGDN/SPACE Navigate q/ESC/CTRL+C Exit browser For multiple event sessions: TAB/UNTAB Switch events For symbolic views (--sort has sym): -> Zoom into DSO/Threads & Annotate current symbol <- Zoom out a Annotate current symbol C Collapse all callchains d Zoom into current DSO D Show some developer debug info E Expand all callchains F Toggle percentage of filtered entries H Display column headers i Show header information P Print histograms to perf.hist.N r Run available scripts s Switch to another data file in PWD t Zoom into current Thread V Verbose (DSO names in callchains, etc) z Toggle zeroing of samples / Filter symbol by name > Also, there's now a GUI inconsistency with perf report: which will now exit > on > Ctrl-Z. It should probably print a warning in the status line instead, that > freezing/unfreezing only works in 'perf top'.
