Placeholder menu
When you translate a segment that contains a placeholder, Google Translator Toolkit automatically shows the Insert HTML tags drop-down list for HTML and other rich text:Open the drop-down list to view the placeholder text.

Click any single tag to paste the tag into the current segment. Or type the tag text directly into the segment.
Placeholder context
Sometimes, placeholders may be ambiguous or difficult to place in the document. For example, consider the HTML text:
Click <a href="docs.google.com">here</a> for Docs and <a href="www.gmail.com">here</a> for Gmail.
which is displayed as
Click here for Docs and here for Gmail.
In this example, the placeholder menu would show:
Insert link: {0}here{/0}
Insert link: {1}here{/1}
To get more context for where to add placeholders into the text, hover your mouse over the placeholder to see the context around the tag. For example, if you hover your mouse over the first 'Insert link,' the tooltip will show:
Click {0}here{/0} for Docs and here f
where 'Click' represents the 20 (or fewer) characters that precede the opening placeholder, and ' for Docs and here f" represents the 20 (or fewer) characters the follow the closing placeholder.

Similarly, if you hover your mouse over the second 'Insert link,' the tooltip will show:
k here for Docs and {1}here{/1} for Gmail.
