Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

2217 Time Zone V (EST) 7 Nov. 1970--NTC-- "Pop's Place": I was polishing a brandy snifter when the Unmarried Mother came in. I noted the time---10:17 P. M. zone five, or eastern time, November 7th, 1970. Temporal agents always notice time and date; we must.

The Unmarried Mother was a man twenty--five years old, no taller than I am, childish features and a touchy temper. I didn't like his looks---I never had---but he was a lad I was here to recruit, he was my boy. I gave him my best barkeep's smile.

Maybe I'm too critical. He wasn't swish; his nickname came from what he always said when some nosy type asked him his line: "I'm an unmarried mother." If he felt less than murderous he would add: "at four cents a word. I write confession stories."

If he felt nasty, he would wait for somebody to make something of it. He had a lethal style of infighting, like a female cop---reason I wanted him. Not the only one.
