With spellcast gone, is there a way to windower command spells?

Haven't played in a long time. I miss being able to //cure5 instead of /ma "Cure V" <t> which no longer seems to be available since Spellcast has been replaced with GearSwap(Gearswap is amazing BTW). Are there any addon/pluggins that have that same functionality? 

Having multiple such a diverse set of features in a single plugin made it difficult for people to get just the things they want. Many people who would have otherwise used the quick-aliases in Spellcast were scared off by the complex scripting system, for instance. So, the feature set of Spellcast was split into multiple addons, each one focusing on just one of the features Spellcast had. Gearswap implements the scripting portion, InfoReplacer provides the seldom-used feature of replacing variables in outgoing chat, and the addon you want, Shortcuts, provides quick-aliases and target completion.
