It is impossible to use shortcuts in WordPress or forums
When I tried to use shortcuts when insert text in WordPress or forums, Vivaldi reacts to shortcuts which are for the text formatting. For example: Ctrt+B = Bold text but = open bookmarks; Backspace = instead of delete text, this shortcut execute "go to previous page". This is very, VERY annoying and ruin my speed of productivity!
@kayovas For now, edit your shortcuts to Ctrl Shift B to open bookmarks.
