I had this idea: https://pharo.fogbugz.com/f/cases/13128/Use-Spotlight-to-quickly-evaluate-an... now you can do <shift-Enter>:42<Enter> to inspect the magic number 42 <shift-Enter>:1500*1.25<Enter> to quickly compute your 25% raise <shift-Enter>:Float pi<Enter> to see how many decimals you still remember <shift-Enter>:ZnClient new get: 'http://zn.stfx.eu/zn/small.html'<Enter> and so on. The interaction with the completion menu is not 100% perfect, but pressing <Space> at the end before <Enter> solves that. Feedback ? Sven PS: I know that many Smalltalk greybeards type everywhere to the same effect, and that is cool to, but it leaves around dirty windows. Opening a workspace for a single expression often is overkill. This feature is totally keyboard driven and very clean. PS2: Yes it resembles Emacs' M-: (evaluate-expression), but Pharo is much cooler, right ;-)
