+| `"\C-?"`      | ctrl + shift + / | backward-delete-char | backward delete a character        |
+| `"\C-u"`      | ctrl + u         | undo                 | clear current line |

+| `"\C-k"`      | ctrl + k         | kill-line            | delete all characters from the current cursor to the end of the line   |
+| `"\C-i"`      | ctrl + i         | complete             | Auto completion, equivalent to `TAB`   |
+| `"\C-j"`      | ctrl + j         | accept-line          | end the current line, equivalent to `enter` |
+| `"\C-m"`      | ctrl + m         | accept-line          | end the current line, equivalent to `enter`     |
+| `"\C-w"`      |                  | backward-delete-word |                  |
+| `"\C-x\e[3~"` |                  | backward-kill-line   |                  |
+| `"\e\C-?"`    |                  | backward-kill-word   |                  |
+
+
+* You can enter `Tab` to get automatic prompts at any time.
+* After typing the command, type `-` or `--`, then press `tab` to display the specific options of this command.
+
+
+#### Custom shortcuts
+
+Create a new `$USER_HOME/.arthas/conf/inputrc` file in the current user home directory and add a custom configuration.
+
+Suppose I am a heavy user of vim. I want to set `ctrl+h` to the cursor forward character. Set it as follows, first copy the default configuration.
+
+```
+"\C-a": beginning-of-line
+"\C-e": end-of-line
+"\C-f": forward-word
+"\C-b": backward-word
+"\e[D": backward-char
+"\e[C": forward-char
+"\e[B": next-history
+"\e[A": previous-history
+"\C-h": backward-delete-char
+"\C-?": backward-delete-char
+"\C-u": undo
+"\C-d": delete-char
+"\C-k": kill-line
+"\C-i": complete
+"\C-j": accept-line
+"\C-m": accept-line
+"\C-w": backward-delete-word
+"\C-x\e[3~": backward-kill-line
+"\e\C-?": backward-kill-word
+```
+
+Then replace `"\C-h": backward-delete-char` with `"\C-h": backward-char`, then reconnect.
+
+#### Shortcuts about async
+
+* ctrl + c: Terminate current command
+* ctrl + z: Suspend the current command, you can restore this command with bg/fg, or kill it.
+* ctrl + a: Go to the beginning the line 
+* ctrl + e: Go to the end of the line
