ui: neutral wording in code and help text; keywords first in the command menu

Comments and the Options help text describe the behaviour of commercial
solutions without naming any product. The command menu puts the command's
keywords directly under Enter / Cancel, with Recent Input and Snap
Overrides below them, so the choices that change from step to step are the
closest to the pointer.
