Hello,
I found that shift-Tab (K_SH_TAB) is a K_SPECIAL key (3 bytes), like
Back-space, that has code 08H.
At the end, in normal.c the K_SPECIAL keys are compared with:
#define K_S_TAB TERMCAP2KEY('k', 'B') ===> -17003 value => 128,107,98 bytes
#define K_BS TERMCAP2KEY('k', 'b') ===> -25195 value => 128,107,66 bytes
What is the code of Shift-Tab after call of inchar function in getchar.c ?
here :
...
/*
* get a character: 3. from the user - get it
*/
wait_tb_len = typebuf.tb_len;
c = inchar(typebuf.tb_buf + typebuf.tb_off + typebuf.tb_len,
typebuf.tb_buflen - typebuf.tb_off - typebuf.tb_len - 1,
!advance
? 0
: ((typebuf.tb_len == 0
|| !(p_timeout || (p_ttimeout
&& keylen == KEYLEN_PART_KEY)))
? -1L
: ((keylen == KEYLEN_PART_KEY && p_ttm >= 0)
? p_ttm
: p_tm)), typebuf.tb_change_cnt);
...
Thanks a lot !
Best regards !
