For the reason you provide, I again suggest using a different shortcut than the one(s) you have. I have had shortcuts act this way, seemingly anomalously giving a result I didn't want, until I realized that I had created a similar shortcut and forgotten it. The same may apply with macro shortcuts, where a 2-stroke shortcut intervenes while I am trying to type a 3-stroke one, because the first 2 strokes were the same.
