+In <TT>fterfirstA`A=95 _ `A=58 : A
+ <`<=95 _ `<=58 : <
+ u@nderscorehyph<271>>UTO_WRITE</TT> mode, once a slider is touched (for MusE-GUIs) or

+<P>
+In <TT>fterfirstA`A=95 _ `A=58 : A
+ <`<=95 _ `<=58 : <
+ u@nderscorehyph<271>>UTO_TOUCH</TT> (and currently (r1492) <TT>fterfirstA`A=95 _ `A=58 : A
+ <`<=95 _ `<=58 : <
+ u@nderscorehyph<271>>UTO_READ</TT>, but
+that's to be fixed) mode, once a MusE-GUI's slider is pressed down, the
+corresponding control is disabled. Once the slider is released, the
+control is re-enabled again. Checkboxes remain in "disabled" mode,
+however they only affect the recorded automation until the last toggle
+of the checkbox. (Example: start the song, toggle the checkbox, toggle
+it again, wait 10 seconds, stop the song. This will NOT overwrite the
+last 10 seconds of automation data, but everything between the first
+and the last toggle.). For native GUIs, this is a bit tricky, because
+we don't have direct access to the GUI widgets. That is, we have no
+way to find out whether the user doesn't touch a control at all, or
+whether he has it held down, but just doesn't operate it. The current
+behaviour for native GUIs is to behave like in <TT>fterfirstA`A=95 _ `A=58 : A
+ <`<=95 _ `<=58 : <
+ u@nderscorehyph<271>>UTO_WRITE</TT> mode.
