   @FrankChen021, thanks much for the explanation. Yes, I agree that the pop-up list exists: it was noted in the description. The key is that I have to know the function name ahead of time. For example `FLOOR` is commonly a function for converting floats to ints, so us newbies wouldn't expect it to be the name of a date-time function. Thus, some kind of UI tool to show functions grouped by category would help when we don't know the name.
   
   Note also that this pop-up disappears once I type the opening paren. But, that is exactly the time when the parameters are needed. Type "time_" pick TIME_CEIL, type "(". Pop-up is gone. What are the parameters again? That is one of the issues described here.
   
   Yes, a workaround is to start a new expression with the same function, see the parameter list again, and go back and fill in the parameters for the first function. Highly awkward, but I agree that it technically works. 
   
   Of course, I find it easier to keep a tab open with the SQL documentation rather than fuss with the UI. This request is to modify the UI so I don't need to have that doc. tab open.
