Google-docs – Entering a “Tab” character into Google Docs, when your document has columns

I am working with a two-column document in Google Docs. The 1st column is a field description. In the 2nd, wider column, I have free text to complete the field information. In this column, I have setup a left tab stop, so some information lines up near the far right of the column. However, I cannot enter a "tab" character to get the text to move to this new tab stop. If I hit the "Tab" key, I jump to the next column entry.

How can I insert a "tab" whitespace character? Ctrl-Tab/Shift-Tab/Ctrl-i – nothing I've tried to-date works.
