I know the author of the documentation has some control over relative font sizes, but I would love as a user to be able to zoom in or out while using khelpcenter - similar to how I can type Ctl+ or Ctl- in most browsers. KHelpCenter Version 6.0.24081 KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.7.0 Qt Version: 6.7.3
You can Ctrl+mouse wheel to zoom in/out. Is that enough?
Yes, that works fine. I'll accept either leaving this as a wishlist for keyboard equivalent, for closing it as not worth the effort. Not sure why I didn't think about trying it - I suppose I'm too stuck with thinking keyboard and not touch or mouse.
Updated the title here, as the Ctrl+mouse wheel-only approach means there is not currently a way to zoom in / increase font size using the keyboard, including via the menus.
