There are two ways to fill in the hotspots.

For example, if you create a snippet:

Snippet TriggerText: html-sim
Snippet Content:

<title>$[![]!]</title>
<body>
    <h1>$[![]!]</h1>
    <p>$[![]!]</p>
</body>

When you trigger this snippet by typing html-sim and hit [tab]. This snippet will be triggered as usual and the caret will stay in in title tag.

<title></title>
<body>
    <h1>$[![]!]</h1>
    <p>$[![]!]</p>
</body>

However, if you type html-sim(MyTitle) and hit [tab]. The snippet will be triggered and the text "MyTitle" will be filled into the first hotspot in sight.

<title>MyTitle</title>
<body>
    <h1></h1>
    <p>$[![]!]</p>
</body>

In other words, you can "pass parameters" to snippets when you trigger them. You can pass in as many parameters as you like. For example, if you type html-sim(MyTitle,MyHeading) and hit [tab]. The text "MyTitle" and "MyHeading" will be filled into the first 2 hotspots. And the caret will goto the p tag.

<title>MyTitle</title>
<body>
    <h1>MyHeading</h1>
    <p></p>
</body>

This feature allows you to create more generic snippets. For example, instead of creating a snippet for each type of tags in html, you can create a snippet named "tag"

Snippet TriggerText: tag
Snippet Content:

<$[![tagname]!]>$[0[]0]</$[![tagname]!]>

If you type tag(body) and hit [tab], you will see that the snippet is triggered and the text "body is filled in.

<body></body>

And if you type tag(abc) and hit [tab], the text abc will be filled in to the tagname

<abc></abc>

Therefore this snippet "tag" can be used to generate any kinds of tag. Notice that this example also shows that Multiple Identical Hotspots works seamlessly with parameter passing.
