=== Dyalog Overrides Current Keyboard Settings === | |||
By default, Dyalog APL overrides the current [https://www.x.org/wiki/XKB/ XKB] configuration to use the Meta ("Windows") key as the modifier for entering APL symbols. If the user manages their keyboard configuration manually using the techniques described on this page, this behavior can be quite troublesome. | |||
To run Dyalog without overriding ("hijacking") the user keyboard configuration, run <code>dyalog</code> with the <code>nokbd</code> option: | |||
<source lang=bash> | |||
dyalog -nokbd | |||
</source> | |||
