How can I easily allocate sales tax to split items (Q Mac)

BP522

After many years of using Quicken for Windows, I recently switched to the Mac Version. Often when I shop at places like Costco or Walmart, I will enter the purchases as a split and allocate the cost to appropriate categories (e.g., groceries, clothing, tools). The receipts apply sales tax to the total purchase. I would like to allocate sales tax to the split items. In the windows version, I entered the untaxed amount, then clicked the calculator icon. I then clicked the +. 5, % keys to add 5% sales tax to the amount. I don't see how to simply do that in the Mac version; there's no apparent equivalent to the % key. With the Mac calculator I have to enter the base amount twice - once to multiply it by the tax rate to compute the tax and then enter again to add it to the computed tax to get the "with tax" total. Am I missing something?

Duh! Thanks.
