问题
When I am typing code in Eclipse, i am using 'TAB' key to jump to expected position, highlighted with green cursor.
For example, if I am typing System.out.println("Some text"|), when I am at position just after the word "text", that "vertical bar" key is highlighted green, so if I press 'TAB' key, my cursor will jump to that position. As expected.
Now, I know that if I press 'ESC', that green "vertical bar" will disappear, actually that proposing position feature is turned off. My question is which keyboard key turns this feature back on?
回答1:
Yes IMHO there is no way to turn on place holders back after they disappear. However you can cycle through forward or backward these place holder by pressing TAB and Shift + TAB keys when they were active.
