 If dwl is [patched](https://lists.sr.ht/~raphi/public-inbox/patches/39166) appropriately, dwlb is capable of communicating directly with dwl. When ipc is enabled with `-ipc`, dwlb does not read from stdin, and clicking tags functions as you would expect. Ipc can be disabled with `-no-ipc`.
 
 ## Commands
-Command options send instructions to existing instances of dwlb. All commands take at least one argument to specify a bar on which to operate. This may be zxdg_output_v1 name, "all" to affect all outputs, "selected" for the current output, or "first" for the first output in the internal list.
+Command options send instructions to existing instances of dwlb. All commands take at least one argument to specify a bar on which to operate. This may be zxdg_output_v1 name, "all" to affect all outputs, or "selected" for the current output.
 
 ### Status Text
 The `-status` command is used to write status text. The text may contain in-line commands in the following format: `^cmd(argument)`.
