Steps to reproduce the issue:
1. Open a file with code in it.
2. Hit Ctrl+L or whatever your GOTO keybinding is set to.
3. Type an existing line number into the toolbar field.
4. Hit return - it does nothing.
Expected result: I would expect hitting return would take you to the line number entered. Instead, I have to grab the mouse and click the button next to it ("Jump To").
You havn't said which version of Geany, on which platform, and it works for me.
1.24 (git >= f81bf99) on Linux Mint MATE Debian Edition
I tried disabling all of my plugins and enabling them one at a time, wondering if maybe one of the plugins was causing the bug. However, after re-enabling all of the plugins, I can't reproduce the issue now, so I'll close the bug for now. Sorry, I don't know what could be different from before.
Oh, I guess I can't close tickets... sorry.
Also, I thought when filling out the bug the version was included, but here it says I put it as a milestone. It was my intention to indicate the version instead.
