Searching IntelliJ / Android Studio using cmd-shift-f injects random characters into search box

Question

For the last six months I have had the most annoying issue with IntelliJ (Android Studio), every time I press cmd-shift-f to do a global search the search box will come up, then about one second later a bunch of random characters will appear in the box. To make matters worse if you type text into the box anything you type will be overwritten. I have no idea what is causing it, putting the random string into Google yields no results however it is the same string every time. Over time I have just learned to wait until the characters appear, then I remove them and type my query but this is killing my workflow. I keep checking Google and Stack Overflow every so often but have found nothing.

This morning I pressed the cmd-shift-f key combination to search and I spotted a GPGTools dialog briefly appear. It turns out GPG tools was trying to inject my fingerprint this whole time. The combination cmd-shift-f is used by GPGTools, and once I knew what to search for I found this post that fixed the issue:

GPGServices had a binding for the key combo in question (Cmd-Shift-F), which happened to be "OpenPGP: Insert my fingerprint." I don't think I mentioned it before, but that's actually what the surprising dialog did: inserted the fingerprint of whatever key I picked into the "what-to-search-for" field of the IntelliJ search dialog. And to confirm the diagnosis, unchecking this setting in the SysPrefs Keyboard Shortcuts does keep the dialog from appearing.
