Here are some useful aliases. It's not complicated at all... Not even by far, but a lot of people ask (me or my frieds) how to open up urls in another browser than their default one. This could be extended to any other browser. Please keep in mind that you might have to change .exe to the browser's full path ("C:\path\to\browser.exe" instead of browser.exe). It works perfectly for me, but you never know
alias firefox { run firefox.exe $1- }
alias ie { run iexplore.exe $1- }
alias opera { run opera.exe $1- }
