Often times, you'll need to create a transaction that utilizes funds that are within a restricted fund. Restricted funds can be used in any transaction that an asset can be used in to either add money to or take money from the restricted fund. Whenever you use a restricted fund within a transaction, the balance of the asset account the restricted fund is attached to will be affected in the same way. So, for example, if you write a transaction against a restricted fund to pay a bill, the asset account the restricted fund is a attached to, and then restricted fund itself will be reduced.
The exception to this is if you're moving money between the unrestricted account of an asset account and a restricted fund under the same asset, or between restricted funds under the same asset. The balance of the asset account itself will not change, but the balance of the restricted fund(s) and the unrestricted fund will change.
