Improve keyboard navigation
Currently, Arm has an inconsistent interface. Some functions (like nterval) produce a menu that can be traversed with the arrow keys. Some (like graph ounds) sysle through the possible options. Some (like log vents) provide a menu that must be navigated by key-entry. Some standardization would be nice.
A desirable interface* would be a hotkeyable menu. That is, rather like the nterval menu, but with a particular hotkey for each entry, perhaps indicated in bold.
*where possible, admittedly this is difficult with functions like log vents
