Via a comment by fastfreddy, got a tip that you can edit the Auto complete plugin to include aliases in the search.
This is the template file to edit:
$:/plugins/snowgoon88/edit-comptext/config{
"configuration": {
"caseSensitive" : false,
"maxMatch" : 8,
"minPatLength" : 2,
"triggerKeyCombination" : "^ "
},
"template": [{
"pattern": "[[",
"filter": "[all[tiddlers]!is[system]][has[aliases]get[aliases]enlist-input[]]",
"start": "[[",
"end": "]]"
},
{
"pattern": "||",
"filter": "[all[tiddlers]!is[system]][has[aliases]get[aliases]enlist-input[]]",
"start": "[[|",
"end": "]]",
"startOffset" : 2
},
{
"pattern": "{{",
"filter": "[all[tiddlers]!is[system]][has[aliases]get[aliases]enlist-input[]]",
"start": "{{",
"end": "}}"
}
]
}
I added a section for the default transclusion operater {{ … }}.
Should look at the inc macro too?
