Since installing Android Studio 3.3RC3 from the preview site, the Theme Editor is missing. When viewing my styles.xml file, there is no button to open the theme editor.
Pressing SHIFT twice and searching for the Theme Editor reveals the icon, but when the pane comes up it shows a blank text editor.
According to this issue, the Theme Editor has been disabled.
The fact that you get something with the double-shift search option suggests that there is a bug somewhere, as if the Theme Editor is an ex-feature, it should not show up in searches either.
Theme Editor is still missing in 3.5 edition. The fact that it hasn't made itself back in makes me think it's been permanently cut. A real shame when there is not a good replacement. It's still possible to edit the theme directly through the styles.xml file, but you will need to look up the syntax yourself for each component.
This article does reference the name of several of the components as well as what they are in project: http://www.informit.com/articles/article.aspx?p=2467490&seqNum=5
