Mac Dictionary improvements I tend to use the dictionary a lot on the mac. Its annoying to launch the app everytime i need to lookup a word. Are there any other apps/hacks to avoid this annoyance? Spotlight lookup is awesome, but doesnt show enough detail. Do you know any app that can provide a panel view for dictionary definitions. For example, launch bar has a nice panel view for its calculator results.
Try ^+⌘+D while selecting a word (that's ctrl+cmd+d). If the app is well integrated into Mac OS X, it will show a little popup with the word definition.

Like so



If you click "More..", it'll open the dictionary app.

If this shortcut doesn't work, go to 

System Preferences > Keyboard > Keyboard shortcuts > Services

and search Look Up in Dictionary to add the shortcut you want.
