It would be nice to have the same help that the Build other projects text box gives when adding downstream projects to Trigger parameterized build on other projects. Also it would be nice to have some kind of validation when leaving the field, so i can see that ive entered the names correctly.

Steps to reproduce

• Create one job named "Alongname"
• Create second job
• Enable Trigger parameterized build on other projects and start editing the edit box
• Write A

Expected outcome:
The textbox would show the projects which names starting with A

Actual outcome:
No help
