WM_keymap_add_item(keymap, "TEXT_OT_insert", KM_TEXTINPUT, KM_ANY, KM_ANY, 0);
<--- this catch-all key map item at the end of the Text Editor keymap was
gobbling all the key events for user-defined hotkeys added after it in the
keymap. This includes all hotkeys for new operators defined by addons (via
keymap.keymap_items.new()).
As a slightly hacky workaround for this, I've added an extra parameter to
keymap_items.new() which will force the newly added item to get added to the
start of the key map items list (i.e. with top priority). To enable, simply add,
head=True to keymap_items.new() calls. For example:
keymap.keymap_items.new("MY_OP_my_operator_id", type='E', value='PRESS',
alt=True, head=True)
This should be useful for cases where there are similar catch-alls, where it is
necessary to insert our item before the offending catch-all (without knowing
which one it is). However, in general, it's recommended not to use this, unless
all other methods (inlcuding choosing another key combination if your first
choice doesn't work) fails.
