My updated Tmux config

Tmux is a great alternative to gnu screen. I’ve previously posted my cygwin tmux config in 2020, and I figured I’d update with my additions since then, including running under real linux. So here it is. Its features include:

• Uses ctrl+a, like gnu screen, instead of ctrl+b
• Mouse interaction is enabled
• Tab bar/windows:
  • Current tab is highlighted in cyan
  • Cycle through tabbed windows with a click on its tab or ctrl+shift+alt+arrow_keys
  • Reorder tabbed windows with a drag of its tab or alt+arrow_keys
  • ctrl+a,/ to rename a tab on the tab bar
  • Create new window with ctrl+a,c
• Panes
  • Create split panes with vertical=ctrl+a,| and horizontal=ctrl+a,- (and start in the cwd)
  • Move around panes with click or ctrl+shift+arrow_keys
  • Resize panes by dragging on the separator bar or use alt+shift+arrow_keys
  • Swap panes directionally with alt+arrow_keys
  • Panes automatically resize to fit OS window
• Clipboard/highlighting
  • Copy text to clipboard by highlighting it
  • Paste from clipboard with right click
  • Middle mouse button+drag highlights and copies too. I did this since nano takes over normal mouse click+drag.
• Copy mode
  

  Key*	Action
  Ctrl+PageUp	Start copy mode, scroll page up
  Ctrl+PageDown	Start copy mode
  Enter	Copies selected text to clipboard and ends copy mode
  Shift+(Left/Right)	Starts selection mode on previous/next character (or continues selection navigation like normal left/right)
  Escape	If something is selected, end current selection. Otherwise, exit copy mode
  Ctrl+(Home/End)	Go to top/bottom of the buffer
  Ctrl+(Left/Right)	Moves to previous/next word like when not in copy mode
  Ctrl+F3, Ctrl+F3	Start incremental search in copy mode
  F3/Shift+F3	Search next/previous (Note, if you use gnome-terminal it may override this)

  * When bolded/cyan the key is for when in copy mode
• Start the session on the current bash directory
• Escape time is lowered for quicker response to copy mode access

To use this, save the file to ~/.tmux.conf

Taking screenshots of Google Maps [Street View]

The following are the steps to take a screenshot without overlays inside Google Maps Street View or Google Maps.

1. Collapse the left side window if visible with the arrow
2. Press F11 to go full screen
3. Open up the dev console [F12]
   Optional: You may need to open the dev console in another window (undocked). Leaving it docked with the window could cause problems.
4. Run the following command in the dev console:
   

   document.querySelectorAll('*').forEach(el => el.style.display='none');
   for(let c=document.getElementsByTagName('canvas')[0];c.parentNode;c=c.parentNode) c.style.display='';

   This should be pretty foolproof, but you may need to change the [0] to another number if the primary canvas element isn't the first canvas.
   
   If that doesn't work, you can also try the following, which is a bit more specialized, but may not catch all the elements on the screen (including the Google logo).

   document.querySelectorAll('[jsaction^="mouseover:"],[jsaction^="mouseout:"],button,[role="navigation"],.scene-footer-container,#omnibox-container,[aria-label="Sign in"],[aria-label="Google apps"]')
   	.forEach(el => el.style.display = 'none');
   document.querySelectorAll('[aria-label="Interactive map"]').forEach(el => el.parentNode.style.display='none');

5. Close the dev console (or Alt+tab back to the chrome window if undocked)
6. Move the mouse to the sky (or a portion that won't trigger possible popups)
7. Wait for a few seconds for icons to disappear
8. Take screenshot

Goodbye Pidgin

You served me well for 15 years.
