<code>Super-<number></code> will go to that number\nworkspace, <code>Super-m</code> will take me to the\nnext free workspace, <code>Super-t</code> will rename a\nworkspace, <code>Super+\\</code> will search workspaces\nnames, etc.</span></p>\n<p><span>I often use <code>Super+`</code> to switch <code>back_and_forth</code> between workspaces, but sometimes\nI’m working between 3 or more workspaces and I get a bit\nlost.</span></p>\n<p><span>I’m used to <a href=\"vim.html\">vim</a>’s jumplist behaviour so I wrote <a href=\"https://github.com/RyanGibb/i3-workspace-history/\">i3-workspace-history</a>\nto replicate this behaviour in sway/i3. It uses a daemon to listen for\nworkspace changes through sway/i3’s Inter-Process Communication (IPC)\ninterface and keeps track of workspace history, and a client which can\ntravel back and forth through this history.</span></p>\n<p><span>Using it is as simple\nas,</span></p>\n<pre><code>exec i3-workspace-history -sway\n\nbindsym $mod+i exec i3_workspace_history -mode=forward -sway; exec st workspace -t 500\nbindsym $mod+o exec i3_workspace_history -mode=back -sway; exec st workspace -t 500\n</code></pre>\n<h2>Conclusion</h2>\n<p><span>There’s a hundred other tips and tricks\nin my configuration which you can find <a href=\"https://github.com/RyanGibb/nixos/tree/master/home/gui/wm\">here</a>.</span></p>",
