I couldn't see your screenshot very well, but it looked to me like you had added 'alias' in front of 'cmdlist'.
That would be the proper format if your alias were on the Remotes tab.
The picture looked like your alias was on the Aliases tab, where you don't need to begin it with 'alias'.
Which is what LittleJohn said.
It should have worked from the Aliases tab as you had posted it.
As long as there is a space between 'cmdlist' and '{', it ought to work. Your post showed a space there, and it worked for me from my Alias tab.
On the Alias tab, take out the word 'alias', then click the button at the upper right that has '{}' on it. If you have a bracket mismatch it will say so. If you don't get an error message, I'm a bit stumped as to what the problem would be.
