I like this, to further minimise hard coding of alt, & ctrl. Yet there are probably a small number of shortcuts with cross platform conflicts where hardcoded values are still required, and for those it even be useful to hardcode AltException & CtrlException rather than Alt & Ctrl - to make this clear to anyone using the system code as an example - but maybe that would be taking it too far. cheers - > > Doru > > >> Cheers, >> Henry >> >>> On 17 Jun 2016, at 2:35 , Tudor Girba <tudor(a)tudorgirba.com> wrote: >>> >>> Hi Nicolai, >>> >>> I am a bit removed from the code details at the moment, and I think I need to step back a bit :). >>> >>> If I understand correctly, you are saying that: >>> 1. defining bindings with #alt does not work on Windows.

Pharo 5.0 Tiny Feature Request

by Sean P. DeNigris

I know our policy is to only backport severe bug fixes, but I have one method I'd like added to 5.0 which would make my life a lot easier. Since NBMacShell has been removed, there doesn't seem to be a built-in way to send simple shell commands, which has broken all my project/image load scripts. I propose the following addition which will restore that basic functionality: LibC class>>system: command ^ self ffiCall: #(#int #system #(#char #* #command)) module: self It doesn't change any existing behavior, so seems relatively risk-free.
