Question

I'm trying to get the value qty of products shipped to display as an additional column in the invoice report. Not sure if its as simple as finding out what variable it is or what. Is there any easy way to reference what variables are available for the current views?
<table class="table table-condensed">
<thead>
<tr>
<th>Description</th>
<th class="hidden">Source Document</th>
<th class="text-right">Ordered</th>
<th class="text-right">Shipped</th>
<th class="text-right">Backorder</th>
<th class="text-right">Unit Price</th>
<th t-if="display_discount" class="text-right">Disc.(%)</th>
<th class="text-right">Extended Price</th>
</tr>
</thead>
<tbody class="invoice_tbody">
<tr t-foreach="o.invoice_line_ids" t-as="l">
<td><span t-field="l.name"/></td>
<td class="hidden"><span t-field="l.origin"/></td>
<td class="text-right">
<span t-field="l.quantity"/>
<span t-field="l.uom_id" groups="product.group_uom"/>
</td>
<td class="text-right">
<span t-field="o.delivery_count"/>
</td>
<td class="text-right">
</td>
<td class="text-right">
<span t-field="l.price_unit"/>
</td>
<td t-if="display_discount" class="text-right">
<span t-field="l.discount"/>
</td>
<td class="text-right">
<span t-field="l.price_subtotal" t-options="{"widget": "monetary", "display_currency": o.currency_id}"/>
</td>
</tr>

I don't exactly know what you mean with "products shipped" but you can get the quantity of the invoice lines to your report like this:
<t t-foreach="o.invoice_line_ids" t-as="l">
<span t-field="l.quantity"/>
</t>
Same for the stock picking lines quantity:
<t t-foreach="o.move_lines" t-as="l">
<span t-field="l.product_uom_qty"/>
</t>
One easy way to get the variable names is to activate the develop mode and placing the cursor over a field label.
You can also go to Settings->Database Structure->Models then just pick your needed model to see the variable names (field names).
