How do I revert the character formatting to the default while entering text?
Example : you enter text with default formatting, then with an underlining for a while. After that, you want to return to default formatting.
In this example, you have pressed the key combination Ctrl+U before "then". To come back to the default formatting, press the key combination Ctrl+U immediately after "while".
It is always possible to disable a property by pressing the same keys that activated it, here Ctrl+U and use Ctrl+M or ⇧ Shift+Ctrl+X to remove all the font effects (italic, bold, underlined, strikethrough, ...) or▸ (or Default formatting for the older versions).
