I found myself doing a particularly intense stint of work the other day, finally had all the source documents and the destination program all lined up, happily finding and comparing and synthesizing and entering, and I realized it was going to take all night. Or realistically until the middle of the next day.
I put the laptop into airplane mode, to block any updates that might unceremoniously reboot it and wreck my layout. Figure if I needed to be on Teams in the meantime, I've still got a phone for that.
Airplane mode already exists, it's _wonderful_ for this, and I should use it more often. If I'm not actively internetting, just toggle that and the distractions can wait.
