 <h2>Launch Style</h2>
 
-<p>FIXME THE ENTIRE TABLE</p>
+<p>
+  The <dfn>Launch Style</dfn> defines how you interact with the clip's
+  playback. Ardour makes a distinction between pressing a button or a key
+  (the 'down' event for a mouse or the note-on MIDI event) and releasing
+  a button or a key (the 'up' event for a mouse or the note-off MIDI event).
+</p>
+
+<p>
+  You can setup a trigger slot so that you would press a silicon pad on your
+  external grid controller, and Ardour would play the clip in that slot
+  indefinitely on repeat. Or you could set it up so that it would only repeat
+  that clip as long as you are keeping the pad pressed and stop playing it
+  as soon as you stop pressing the pad.
+</p>

 <h2>Launch Quantize</h2>
 
-<p>From 4 bars down to 1/64 bar, and None. FIXME</p>
+<p>
+  This setting defines how long Ardour will wait till beginning the playback
+  of a clip in a trigger slot. If the transport is already rolling, and
+  quantization is set to 1 bar, which is the default, Ardour will wait for the
+  next bar, then start playing the clip. Quantizing to a whole bar or several
+  bars typically guarantees that downbeats of a drums track and a bassline
+  track align.
+</p>
+
+<p>
+  The quantization value can be as large as 4 bars and as small as 1/64 bar.
+  When 'None' is selected, playback with a rolling transport will start
+  immediately.
+</p>
 
 <h2>Legato</h2>
 
-<p>FIXME (also, doesn't work properly yet).</p>
+<p>
+  The <dfn>Legato</dfn> mode helps keeping two clips of the same track in sync
+  when you switch from one to another. With Legato on, Ardour will pick up
+  the playback of the second clip at the position where the first one left off.
+  Please note that quantization applies here.
