H. Kossebau <kosse...@kde.org> --- This is due to the Okular KPart being used in the preview, which is eating the Space key events and uses it for scrolling, despite not having the focus. While there is a principle issue with shortcuts from used KParts plugins conflictiing with app shortcuts, see bug 386265, this here though is a special variant, as the Space key usually is not a shortcut, so this is IMHO some overly aggressive behaviour of the Okular KParts plugin which should get in conflict in more embedding scenarios. So moving to Okular, so they can consider to improve this in their KParts plugin to restrict stealing the space key event only to when the view has focus. Some work-around for Kate and Markdown preview: use kmarkdownwebview KParts plugin, select in SystemSettings > Applications > File Associations > text/markdown > Embedded > Move kmarkdownwebviewkpart to top in order, press Apply. Still has the other shortcut conflict issues. But normal editing and previewing at least can be done as one expects :) -- You are receiving this mail because: You are the assignee for the bug.
