To edit citations, simply click on the field in the right editing pane and make the necessary additions and/or corrections. There is no way to mass change case of multiple fields at once; they need to be changed manually by either retyping or cutting & pasting into Word, using the 'Change case' feature, then copying & pasting back into Mendeley.

Throughout this UAH Library subject guide page for Mendeley, information came from several different sources. Chief among those are the Mendeley research guide pages from Michigan State University Libraries (with a shout-out to Suzanne Teghtmeyer for her great documentation!) and also from the Elsevier library subject guide template.
