[TxMt] Selecting a line without its leading and trailing spaces

[Jon Ippolito]

Is there a key combination for selecting a line (or lines) of code in a tag but
omitting leading and trailing spaces and tabs? I'm familiar with the Shift-Cmd-L
shortcut, but it leaves in the whitespace. This makes a mess of indented HTML
when I'm using the Ctrl-Shift-W and Ctrl-Shift-Cmd-W HTML shortcuts.

In other words, if I apply the combination Shift-Cmd-L followed by Ctrl-Shift-W
to this line:

    Here's a paragraph!

I get this:

<p>    Here's a paragraph!
</p>

instead of what I want, which is this:

    <p>Here's a paragraph!</p>

Obviously I could use the mouse to select only the correct part, but I was
hoping there might be a keyboard shortcut.

If it's best to create my own macro using Regular Expressions, any pointers as
to how to get started would be helpful.

Many thanks!
