htop notes. mostly to myself

The keys I mostly use for htop are:

• 't' to toggle between tree mode (nifty as fuck to find a place to stick an 'exec' and shorten a chain of processes
• 'F6' in non-tree mode to select which column to sort by. PERCENT_CPU is the one I use the most.
• 'space' to mark and unmark a process so you can more easily watch it, or switch to and from tree mode.
• 'k' to send a signal to the currently selected process. gives you a menu on the left to pick which signal.

other things

• 's' to turn on strace. need to actually test this.
