Aspell purposes words when it doesn't know a word in a sentence you write.
You have then some choices:
1,2,...0 = replace the word by the one you choose
i = ignore the word
I ignore all the words (you do nothing)
r = you enter then the word you want, because the good word hasn't been purposed
R = idem as r, but for all the misspelled words
a = add the word you're going to enter to your personnal directory
l = add lower (not tested)
b = abort (you stop and loose the spelling ckeck already made)
x = quit (the job is finished)
Due to the way I use to wait the end of the checking phase, it's important to quit Aspell by using the keys expected for. Never use the windows button to close the window.
I use a batch file which, after spelling check, delete a file created just before launching the batch. The presence of this file is tested by the macro to know if the operation is finished.
If you close the window by using the close button, you stop the batch, and not only Aspell, and the file is never deleted, and K-Meleon is always waiting the deletion, and is blocked. The only ways are then to manually delete the file (located in profile folder (aspell.flg) or to kill K-Meleon.
. ALWAYS QUIT USING X OR B, NEVER USE THE CLOSE BUTTON.
