window (mapping means actually displaying it on the screen), you’d need to have
to match on 'Firefox' in this case.
+You can also assign a window to show up on a specific output. You can use RandR
+names such as +VGA1+ or names relative to the output with the currently focused
+workspace such as +left+ and +down+.
+
Assignments are processed by i3 in the order in which they appear in the config
file. The first one which matches the window wins and later assignments are not
considered.
*Syntax*:
------------------------------------------------------------
-assign <criteria> [→] [workspace] <workspace>
+assign <criteria> [→] [workspace] [number] <workspace>
+assign <criteria> [→] output left|right|up|down|primary|<output>
------------------------------------------------------------
*Examples*:
# Assignment to a named workspace
assign [class="^URxvt$"] → work
+# Assign to the workspace with number 2, regardless of name
+assign [class="^URxvt$"] → number 2
+
+# You can also specify a number + name. If the workspace with number 2 exists, assign will skip the text part.
+assign [class="^URxvt$"] → number "2: work"
+
# Start urxvt -name irssi
assign [class="^URxvt$" instance="^irssi$"] → 3
+
+# Assign urxvt to the output right of the current one
+assign [class="^URxvt$"] → output right
+
+# Assign urxvt to the primary output
+assign [class="^URxvt$"] → output primary

+Also, the arrow is not required, it just looks good :-). If you decide to
use it, it has to be a UTF-8 encoded arrow, not `->` or something like that.
To get the class and instance, you can use +xprop+. After clicking on the
second part is the class ("URxvt" in this example).

laptop, you might have VGA1 and LVDS1 as output names. You can see the
available outputs by running +xrandr --current+.
+If your X server supports RandR 1.5 or newer, i3 will use RandR monitor objects
+instead of output objects. Run +xrandr --listmonitors+ to see a list. Usually,
+a monitor object contains exactly one output, and has the same name as the
+output; but should that not be the case, you may specify the name of either the
+monitor or the output in i3's configuration. For example, the Dell UP2414Q uses
+two scalers internally, so its output names might be “DP1” and “DP2”, but the
+monitor name is “Dell UP2414Q”.
+
+(Note that even if you specify the name of an output which doesn't span the
+entire monitor, i3 will still use the entire area of the containing monitor
+rather than that of just the output's.)

If you use named workspaces, they must be quoted:

video drivers (especially the nVidia binary driver) only provide support for
Xinerama instead of RandR. In such a situation, i3 must be told to use the
inferior Xinerama API explicitly and therefore don’t provide support for
