Not exactly, but you can make it appear that way.
Put the commands in a file somewhere, say, ~/.zhistalways or whatever.
Then in ~/.zshrc, use the command
fc -R ~/.zhistalways
This assumes that ((HISTSIZE > SAVEHIST)), because otherwise the history
read from $HISTFILE will cause those commands to fall off again.
Or you could use
< ~/.zhistalways >> $HISTFILE
instead, to assure that those commands are always the most recent ones.
Either way, I'd recommend setting either the HIST_EXPIRE_DUPS_FIRST or the
HIST_IGNORE_ALL_DUPS options (assuming you're using 3.1.9).
Or you can take a different approach, and avoid using the history at all,
and instead use the completion system (again assuming 3.1.9). I have a
file named "_cmdselect" in my $fpath:
#compdef -k menu-select ^X:
local -a commands
(list of commonly-repeated commands goes here, one per line)
compadd -Q "$commands[@]"
When I run "compinit", it finds that file, autoloads it, and binds it to
the key sequence control-X colon. When I want to use one of my frequent
commands, I type a prefix and then C-x : and the completion system does
the rest; if I didn't make the prefix unique, I get a menu from which to
choose. (If you don't like the menuing behavior, change `menu-select' to
`complete-word' or `menu-complete' in the above.)
