Keyboard Accelerators: The Sports Cars of GUIs

More advanced users often like using keyboard shortcuts for common tasks because they reduce the considerable amount time spent switching between the keyboard and the mouse.

Standard System Accelerators:

[...]

• B_COMMAND_KEY + F: Show find window
• B_COMMAND_KEY + G: Find again
• B_COMMAND_KEY + B_OPTION_KEY + F: Show Replace window
• B_COMMAND_KEY + L: Replace and Find

[...]

How StyledEdit uses the shortcuts

• B_COMMAND_KEY + F: Show find window
• B_COMMAND_KEY + G: Find again
• B_COMMAND_KEY + B_OPTION_KEY + F: Unused
• B_COMMAND_KEY + R: Show Replace window
• B_COMMAND_KEY + T: Replace next
• B_COMMAND_KEY + L: Reload

What I propose:

• B_COMMAND_KEY + F: Show find window
• B_COMMAND_KEY + G: Find again
• B_COMMAND_KEY + B_OPTION_KEY + F: Show Replace window
• B_COMMAND_KEY + L: Replace next
• B_COMMAND_KEY + R: Reload

B_COMMAND_KEY + R as Reload uniform the use with webpositive, weather, ...

This combination can be used in Mail too, see #13163.
