The auto-burst setting (line 19) has been extended further:
19) If 1, Speeder will automatically use your weapon's burst skill when it is fully charged.
Speeder will not use the skill unless you are in combat and the game is the active window.
The skill will be activated with an ALT+1, ALT+2, or ALT+3 keypress depending on which burst skill is active.
If the ALT keypress is not working, you can set the virtual key code manually by using the "|" character. For example:
(line 19:) 1|164
164 is the virtual key code for LEFT ALT. It works for me on a U.S. English keyboard.
If it is STILL not working, you can try one additional setting after another "|":
1|164|1
The second "1" tells Speeder not to treat "164" as an extended key.
