シフトキー
On Linux, the alt key gives direct access to French language special characters. The ligatures œ and æ can be keyed in by using either or respectively, in the fr-oss keyboard layout; their upper case equivalents can be generated using the same key combinations plus the French Shift key. Other useful punctuation symbols, such as ≤, ≥, or ≠ can be more easily accessed in the same way.
