.. section: IDLE
Convert IDLE's built-in 'extensions' to regular features.
-
About 10 IDLE features were implemented as supposedly optional extensions.
Their different behavior could be confusing or worse for users and not good
for maintenance. Hence the conversion.
-
The main difference for users is that user configurable key bindings for
builtin features are now handled uniformly. Now, editing a binding in a
keyset only affects its value in the keyset. All bindings are defined
together in the system-specific default keysets in config-extensions.def.
All custom keysets are saved as a whole in config-extension.cfg. All take
effect as soon as one clicks Apply or Ok.
-
The affected events are '<<force-open-completions>>', '<<expand-word>>',
'<<force-open-calltip>>', '<<flash-paren>>', '<<format-paragraph>>',
'<<run-module>>', '<<check-module>>', and '<<zoom-height>>'. Any (global)
customizations made before 3.6.3 will not affect their keyset-specific
customization after 3.6.3. and vice versa.
