Since there is kind of 2 states to a string iobox and the behaviour is bit different:
just focused/selected
in edit mode (cursor blinking)
At which state is this new behaviour? I fear there is no way then to quickly select all the text? could we have like a triple click then to select all, like it is common in various other software?
I mean beside CTRL-A in edit mode
A double-click selects the word containing the text insertion point; a triple-click selects the line containing the text insertion point; four clicks selects the entire paragraph containing the text insertion point; five clicks selects the entire story.
