Is there a regex shortcut for exactly zero OR one instance? I.E. {0,1}?

In this particular case it needs to be zero times or one time, nothing more (or less if that is possible). {0,1} works well. But I thought that this is such a common thing, at least I have been writing it a lot, that there could be a short cut for it. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/RegEx/message.cfm/messageid:1115 Subscription: http://www.houseoffusion.com/groups/RegEx/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user837.14401.21 |

My brain just did no go there, for some reason I just did not make the equation of 'optional' as the same as '{0,1}'. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/RegEx/message.cfm/messageid:1118 Subscription: http://www.houseoffusion.com/groups/RegEx/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user837.14401.21 |

Possibly being pedantic, but ? is more "1 or 0" - it will match if it's
there, but not fussed if it isn't. "0 or 1" would be the lazy optional ?? which will only match if it has to, but wont if it can avoid it.
