Ctrl + and Ctrl - are universally popular shortcuts to for zoom-in and zoom-out. Ctrl - works in KMail but Ctrl + doesn't. Rather it require Ctrl+Shift++ to zoom-in. Is there a specific reason for using Ctrl+Shift++ instead of Ctrl + to zoom in?
Steps to Reproduce:
1. Press Ctrl + in a message
message is not zoomed-in
Ctrl + should be used for zoom-in in messages
Also KMail shortcut shows keyboard shortcut for zoom-in is Ctrl++ but it doesn't work.
System Locale: LANG=en_IN.UTF-8
VC Keymap: us
X11 Layout: us,in
X11 Variant: ,eng
work fine here.
We use default kde shortcut.
So no idea why you don't have correct shortcut
