What's the shortcut to interrupt the kernel in Canopy?
osx,kernel,interrupt,shortcut,canopy
There is no shortcut for interrupting the kernel. That command, along with restarting the kernel, is in the Run menu, which also shows the shortcut for the restart kernel command. Note that because of the nature of the interaction between Python and C extensions, neither command is guaranteed to work,...
WC on OSX - Return includes spaces

How to set the default writing direction for NSTextView?
osx,swift,cocoa,interface-builder,nstextview
NSTextView inherits from NSText. NSText has a baseWritingDirection property. Try setting that: hebrewTextView.baseWritingDirection = NSWritingDirection.RightToLeft It also inherits the action method makeBaseWritingDirectionRightToLeft() from NSResponder, which presumably what the contextual menu uses. So, you could call that. If neither of those works, you can set the text view's defaultParagraphStyle to one...
