## [LPIC-1]GNU and Unix Commands 19

What is the difference between the i and a commands of the vi editor?

A. i (interactive) requires the user to explicitly switch between vi modes whereas a (automatic) switches modes automatically.
B. i (insert) inserts text before the current cursor position whereas a (append) inserts text after the cursor.
C. i (independent rows) starts every new line at the first character whereas a (aligned rows) keeps the indentation of the previous line.
D. i (interrupt) temporarily suspends editing of a file to the background whereas a (abort) terminates editing.

#### 題解

vi文字編輯器的「i」快速鍵的作用是在游標目前所在位置上進入插入模式。「I」快速鍵會在游標目前所在的該行的最前端位置上進入插入模式。「a」快速鍵會在游標目前所在位置的右邊一個位置上進入插入模式。
