For as long as I can remember (well maybe not quite) I have made use of the run functionality within windows. For the most part you able to run the command/ program/ URL that you want to by simply pressing Windows key and R and then typing what you want to do.
Then came Windows Vista with its new fancy type and filter start bar (.
You are able to pop open the start bar and type what you want, be it a program, file, email or previous command that you have run and it will display in a list above the search so that you can choose what you want to run.
My foray into the use of Windows Vista was cut short with me moving jobs and I am now back to [Windows]+R and Windows XP. Though, in the space of the last week, I have heard of the applicaiton Launchy twice. So I downloaded it and can now say that I am hooked.
By simply pressing [Alt]+[Space] the Launchy window pops up and you are able to type what you want to do and let it suggest programs. From here it is a simple [Enter] and you are running your program.
Congratulations to the creators of a great free app.
