===== Copy =====

**__Resource__:** [[https://www.rushiagr.com/blog/2016/06/16/everything-you-need-to-know-about-tmux-copy-pasting-ubuntu/ | Everything you need to know about tmux copy]]

**To copy outside tmux:** You should be able to highlight with your mouse (shift + left-mouse-button). Once highlighted, go to the program where you want to paste and click the middle-mouse-button.
  * If that doesn't work (sometimes it does... sometimes it doesn't... and that drives me nuts!)...
  * **Shift + Left-Mouse-Button:** This highlights the text you want to copy. Then just go to the window/program into which you want to paste and middle-mouse-button to paste (i.e., Linux default behavior).

**To copy inside tmux:** See the following...

**Key Bindings:**

^ Command      ^ Description       ^
| ''Ctrl-b ['' | enter copy mode   |
| ''Ctrl-b ]'' | paste from buffer |

**Copy Mode Commands:**

^ Command                  ^ Description        ^
| ''Ctrl-[spacebar]''      | start selection    |
| ''Ctrl-w'' or ''Alt-w''  | copy selection     |
| ''Ctrl-[Esc]''           | clear selection    |
| ''Ctrl-g''               | go to top          |
| ''Ctrl-G''               | go to bottom       |
| ''Ctrl-h''               | move cursor left   |
| ''Ctrl-j''               | move cursor down   |
| ''Ctrl-k''               | move cursor up     |
| ''Ctrl-l''               | move cursor right  |

===== Other Stuff =====

==== Mouse Mode ====

Mouse mode allows you to control the pane selection, pane resizing, window selection operation, along with scrolling, with the mouse.

To enable the mouse mode, open the ''~/.tmux.conf'' file and put the following line inside it:

<code>setw -g mouse on</code>

Reload it (whenever you change a configuration file of a running program, like a Bash shell, etc., you need to source it to load it again--or exit and enter again):

<code>tmux source-file ~/.tmux.conf</code>
