Eclipse / STS中的Ctrl 2重构

Question

I read on the blogs about Eclipse's quick assist shortcuts and went ahead to try them out, however only 2 out of the 4 work for me.

When I hit Ctrl+2, STS displays a hint with all 4 of them explained in the right bottom corner:

• Ctrl+2, F - assign to field

• Ctrl+2, L - assign to local variable

• Ctrl+2, M - extract method

• Ctrl+2, R - rename in a file

When I then hit a letter, the expected behavior only works for the last 2 (extract and rename), and not for the first 2 - F and L - to assign to a field or a local variable.

What am I doing wrong?

Here's what I see in Eclipse's General | Keys Preferences:

Answer 1

See Eclipse Preferences General -> Keys page. Perhaps the first two key bindings are mapped to some other actions.
