Slightly shorter:
Code:
sed -n 's/,.*$//; /key1/h; /key2/{H; x; s/^[^:]*: //; s/\n[^:]*://; p} ' file
word1 word5
word8 word10

---------- Post updated at 08:05 ---------- Previous update was at 08:04 ----------

And Scrutinizer's approach will become
Code:
sed -n 's/^.*key[12]: \|,.*$//gp' file | paste -d" " - -

And taking an idea from your 2nd example we get two more equivalent versions that are still slightly shorter:
Code:
sed -n 's/,.*//; /key1/h; /key2/{H; x; s/^[^:]*: \|\n[^:]*://gp}' file

sed -n '/key1/h; /key2/{H; x; s/,[^\n]*\|^[^:]*: \|\n[^:]*://gp}' file

which possibly might even be as short as you can get using a non piped single call to sed.
