Wow -- who would have guessed that? <br>
<br>
Can a contextual lookup refer to Contextual Chaining lookups as
well? Reverse Contextual Chaining lookups?<br>
<br>
Presumably the phrase in the contextual lookup description:<br>
<blockquote type="cite"><span style="color: rgb(0, 0, 0);
font-family: Georgia, 'Times New Roman', Times, serif;
font-size: 13px; font-style: normal; font-variant: normal;
font-weight: normal; letter-spacing: normal; line-height:
normal; orphans: auto; text-align: start; text-indent: 0px;
text-transform: none; white-space: normal; widows: auto;
word-spacing: 0px; -webkit-text-size-adjust: auto;
-webkit-text-stroke-width: 0px; background-color: rgb(255, 255,
255); display: inline !important; float: none;">Because multiple
substitutions may occur per context, the SequenceIndex and
LookupListIndex refer to the glyph sequence after the
text-processing client has applied any previous lookups.</span></blockquote>
still holds, so the referred-to contextual lookup may "see" a
context quite different than original lookup.<br>
<br>
I'm curious how people utilize this?<br>
