Did you know that you can configure any one particular Pick List to make it easy (and consistent) for users to enter in data?
1. Bring up the Pick List for any field you like by clicking into the field and hitting F2.
2. Click on the "Setup" button.
3. Here are a few of the most popular options:
a. Unchecking "Allow Blank Input" will force the end user to enter in a value.
b. Checking "Force Valid Input" will force the end user to enter in a value that matches a Pick List item.
c. Pop-up when selected does what it says; pops up automatically when the end user moves to the field.
have a lot of clients that protect the integrity of the data model with
just a few modifications to existing picklists. My advice is to start
slow with this process; try configuring a few fields at first, then
expand as you get a feel for how the changes affect the end users.
