This showed me that, as I expected, Content Assist was assigned to Ctrl-Space: Helpfully, it’s not called autocomplete or anything like that – it’s called Content Assist. When trying to fix this myself, I went in to the Eclipse options ( Windows-> Preferences, then General-> Keys) and tried to find the command for auto-complete. In the image above (which unfortunately doesn’t include the cursor) I had typed ST, and pressed Ctrl-Space to autocomplete it but nothing happened. So, you type part of a function name and press Ctrl-Space, waiting for the magic to work and the rest of the name to be automatically typed….but it doesn’t happen! You’ve just installed Eclipse, are starting to do some programming in it, and want to use the very handy auto-complete feature.

First of all, let’s see what the problem is: It’s actually very simple to solve, but the problem is actually nothing to do with Eclipse.

I’ve just set up a new University computer and things don’t work like they do on my laptop (maybe that one’s just me…).

Why can’t I get auto-complete to work properly in Eclipse?.
