I don't know if you have a thousand row of code, pull it with a scroll bar, and use the pen to record the experience of the start of the child countless? No? You are more smart than me, I have done it in the past.
Later, when I was developed with JBuilder X, I used the bookmarks to omit the above problems.
The way to set the shortcut is this: Position the cursor to a row, hold down "Shift Ctrl" and a numeric key, such as "0".
So I pressing the key here is "Shift Ctrl 0", which is a label symbol in the editing area. I pulled the scroll bar. When I want to go back to the positioning point, just hold down "Shift" and the numeric key. Here I use "0". That is, "Ctrl 0". Will be directly positioned to the initial location, simple.
