進入group時自動讀 n 個header而不要詢問:

Changes since slrn 0.9.7.4
16. If query_read_group_cutoff is set to -n, slrn will automatically
    (without prompting) download n articles when more than n are present
                                                                                
目前測試結果是v0.9.8.0 OK, 但0.9.7.4的-n無效?
                                                                                
進入group的選項:
from: reference 7.1 group functions
    select_group
    Default: "RETURN" "SPACE"
                                                                                
    Enters the current group for reading. When using a prefix argument,
    this function also downloads previously read articles:
                                                                                
      1 Select group with article number query.
      2 Select group, but do not apply scores.
      3 Select group with query, but do not apply scores.
      4 Select group.

Thread展開時沒看到樹狀圖:
from FAQ 2.6
    If you see strings like ``mq>'' or ``tq>'' instead of a
    thread tree make sure that your terminal or terminal emulator
    supports vt100 escape sequences.
                                                                                
系上設成xterm / xterm-color就OK了,
cons25, linux不行

followup
Default: "f"
                                                                                
Write a followup on the current article.
The following prefix arguments are accepted:
    1   Insert all headers.
    2   Insert all headers, but do not modify the article (no quoting,
        don't strip or attach signatures).
