# dwm: Tags are not workspaces

dwm is a tiling window manager for Linux that I run on my main PC. I prefer dwm over other tiling window managers because its minimalism follows Arch Linux's KISS philosophy.

Out of the box dwm is light, fast and simple. If you want extra functionality - and most users do - you'll edit the source code, recompile and reinstall it.

### Defining tags and workspaces

Users often confuse dwm's tagging system with workspaces (or virtual desktops). Once you understand that tags are not workspaces, you'll realise why dwm was given its name - dynamic window manager - and how powerful it is.

A tag is simply a label placed on windows. A window may have one or more tags. Tags provide no other functionality.

A workspace is the arrangement of windows from one or more tags. One of two workspaces must be active at all times. dwm refers to a workspace as a view.

Hereafter, view will be also used interchangeably with workspace.

### Better keyboard and mouse bindings

Ironically, dwm's default hotkeys are setup in such a way that it actually promotes treating tag-as-views rather than tags-as-tags.

By default, MODKEY + [1-9] will switch the view to to that tag's windows and MODKEY + Ctrl + [1-9] will toggle that tag's windows to/from the current view. When treating tags-as-tags, the latter occurs far more often. It makes sense to switch these keybindings around so that the more common operation requires less keypresses.

Likewise, Button1 clicking a tag number in dwm's bar switches the view to that tag's windows and Button3 clicking toggles that tag's windows from the current view. Again, it makes sense for us to switch these bindings around so that the more common operation is executed with a left mouse click instead of a right.

To do so, make these changes in config.h:

### My workflow: two workspaces

I use 9 tags with rules in config.h for the following:

1. Web browser: firefox
2. Communication: tmux instance (irssi, mutt, transmission-remote-cli)
3. Coding: gvim
4. Documents: libreoffice-calc, libreoffice-impress, libreoffice-writer, zathura
5. Video: mplayer2
6. GUI Editors: gbdfed, gimp, fontforge, inkscape
7. File manager: ranger
8. N/A
9. N/A

I mostly have 2 to 4 windows visible at a time. When a view gets too crammed, I'll re-tag some windows with MODKEY + Shift + [1-9] and toggle those tags' windows into view with MODKEY + [1-9] when needed.

Aside from toggling tags to/from the current view and re-tagging windows , the third most common tagging operation I use daily is MODKEY + Tab to switch between the current and most recent views.

In fact, the only times I use MODKEY + Ctrl + [1-9] to change views is on startup or if my previous view contains windows from all tags after executing MODKEY + 0.

Here's an example.

On startup, the first tag is automatically selected. I hit MODKEY + 2 and MODKEY + 5 to toggle windows from tags 2 and 5 into view:

Then I created a new view with MODKEY + Ctrl + 3 and toggled windows from tag 4 into it with MODKEY + 4:

MODKEY + Tab will now toggle between the first and second screenshots.

From the first screenshot, I toggled tag 3 windows into view with MODKEY + 3 and re-arranged the windows such that the config.h file became the master client, appearing on the left, and the .markdown file became the last client, appearing on the bottom-right.

Toggling tag 3's windows out of the view again with MODKEY + 3 brought me back to the first screenshot. Then MODKEY + Tab got me back to the second screenshot.

From the second screenshot, I toggled windows from tag 1 or 2 into view. Notice that the positioning of the windows is remembered from the third screenshot.

As you'd expect, if I'd toggled windows from both tags 1 and 2 into view, it'd be identical to the third screenshot.

This is what makes dwm's tagging system so powerful. Users are able to dynamically arrange all windows in different ways and it'll always be remembered, regardless of what windows or what tag numbers are visible in the current view.

### Revision: dwm's bar

For those who are still a bit confused, here's some examples to describe the information displayed in dwm's bar.

• A view displaying windows labelled tag 1.
• A tag 1 window has focus.

• A view displaying windows labelled tags 1 and 5.
• A tag 1 window has focus.
• One or more tag 5 windows are visible but not focussed.

• A view displaying windows labelled tags 1, 2 and 5.
• A window that is assigned to both tags 1 and 2 has focus.
• One or more tag 5 windows are visible but not focussed.

• A view displaying windows assigned to tag 3 and tag 4.
• There are no visible windows.
• One or more hidden windows are assigned to tags 1, 2 and 5.
