tcsh oddity

[doug]

I recently had to restore my workstation. As it happened I did not restore 
the /usr/share/skel files, .history is what my question is about. As you 
know <esc>p will match commands earlier typed in with the pattern on the 
line. There are a couple of commands I type incessantly. <esc>p did not 
pick these up immediately, but after a while it has "learned" about the 
commands. However this works it does not seem to be via .commands. Does 
anyone know how tcsh starts "remembering" repeated commands?
