almost always will).
+- RTL and keymaps
+
+Currently there is a bug where you can't use two non-RTL language keymaps if
+the RTL preference is set (which is now the default). If you need to use two
+non-RTL keymaps, for now you should just turn off the RTL preference (Tools ->
+Preferences... -> Language settings -> Language, uncheck "Right-to-left
+language support").
+
+We hope to offer more comprehensive support for multiple keymaps in the future,
+which will solve this bug, as well as allow more than just two keymaps. If you
+have any input on this issue, please chime in on the developers mailing list,
+or add your comments to http://bugzilla.lyx.org/show_bug.cgi?id=4051.
