Luke,
When you go into Input Gestures for Speech Logger, the gesture to turn on logging for local speech is NVDA + ALT + L, but the ell is shown as a lowercase L, which for those of us who are sighted, is indistinguishable from an uppercase I in a very great many fonts (and it is in the one used by NVDA for presenting the Input Gestures dialog).
I have no idea if there are other places where the letter ell is represented by a lowercase variant, but for the sake of sighted assistants who may be helping an NVDA user, uppercase ell is a better choice as it's visually distinguished from uppercase I in any font I've ever seen.
Certainly not a high priority fix, but if you happen to be making any that would allow that tweak, I know I, for one, would appreciate it.
