System Commands
Save time and clicks by typing the System commands in Alfred. Rename the shortcuts to be even shorter if you use certain commands regularly.

Ejecting Removable Media and Mounted Volumes
If Alfred isn't showing mounted volumes, change the setting for the Eject dropdown menu to "Mounts in/Volumes". Note that this feature is only supported in OS X 10.6+.
