Quando eu habilito o NumLock pelo teclado, todos os atalhos do Alt_L (por exemplo, Alt_L + Arrow_L no Firefox) não são executados.
Ao usar o xev, ele me mostra que Alt_L causa perda de foco quando o NumLock está ativo.

Existe alguma maneira de alterar esse comportamento para que eu possa usar NumLock e Alt_L juntos?
