I have to select text. and it doesn't agree with me :) seems like a possible shortcut to implement though - take the current method and work out which message the cursor is sitting on (possibly via AST or similar), jump to it. then another shortcut to "return to previous position" (before the jump). that'd be one of the most common things I do - jump and take a peek at a method and come back.

Adding Websocket support to Zinc

by Andy Burnett

I think we need Websocket support built into Pharo. So, rather than talk about it, I have contracted with Sven to build it into Zinc. We hope to have a running version in the early Autumn. The purpose of this email is: 1. To let everyone know that we will have Websocket support soon 2. To ask if anyone else feels that they would gain commercial benefit from using this feature, and if so, whether they would like to help cover the cost. If so, please drop me an email. Cheers Andy

do not select code just put the cursor on the line and doit get the complete line then you can click once and it will select the complete expression. but as dale said first get used to cmd-m cmd-n cmd-N cmd-b Then the good news is that in pharo 2.0 we will have much more and better shortcuts many of us do not like mouse either :) Stef On Jul 31, 2012, at 8:31 PM, Patrik Sundberg wrote: > Thanks for that list.

Re: [Pharo-users] [pharo 2.0] IP address to ByteArray

by StÃ©phane Ducasse

The problem is that '127.0.23.11' copyUpTo: $. copyUpTo: does not help because what you would like is a method that return '127' and '0.23.11' I could not find one. If you do or define it I would like to add it to the system. Because with it we could do one pass instead of two.
