如何在Eclipse建议弹出窗口中使用键盘主键向上/向下导航？

Question

When Eclipse shows a popup for code completion, how do you change the highlighted option using the keyboard home keys? Currently, if the thing I want is third or fourth on the list of suggestions, I have to use the mouse to select it, or use the arrow keys. Is there a way to use the keyboard home keys/ shortcuts with ctrl/alt to do this?

Answer 1

I'm assuming you want to select from the code completion menu by X for up and Y for down. Go to Preferences > Keys and bind the commands Line Up and Line Down to X and Y , respectively. Make sure that in the When drop-down you select In Windows .

Note that after the settings are applied, X ( Y ) also makes the cursor go one line up (down) in the source editor. Personally, I use X = Ctrl+P and Y = Ctrl+N which means I can navigate lines and select entries from the code completion menu without lifting my hands off the keyboard.

Unfortunately, these bindings don't work with other pop-up lists in Eclipse, eg quick outline ( Ctrl+O ) or quick access ( Ctrl+3 ). I'd love to find out how to bind these too.

Arrow keys always work for me. Can you be little more specific as to what perspective, editor, etc?

I get a code completion popup when I press Ctrl + 1 in the Java editor. From then on, I can use the arrow keys to navigate.
