Fix Shorcuts to match Photoshop CC Behaviour

[pierspad]

Many of the shortcuts currently listed in shortcutsrc do not correspond to the shortcuts that are actually present in Photoshop.

I have updated some of the most used to better adhere to:
Adobe Photoshop CC Shortcuts Reference.
Photoshop Keyboard Shortcuts

---

Key Changes:

• Layer Duplication (Ctrl+J): Remapped from image-duplicate (whole image) to layers-duplicate (active layer).

• Free Transform (Ctrl+T): Mapped to tools-unified-transform instead of Scale. It enables also rotation, similar to Photoshop's Free Transform.

• Fill (Alt+Del / Ctrl+Del): Swapped to correctly match Foreground vs Background fill colors logic.

• Marquee Tools (M / Shift+M): Separated Rectangular and Elliptical selection.

I used a short Python script to clean up and sort the file into "Active" and "Inactive" sections to improve readability.
NOTE: GIMP will load shortcuts in memory and overwrite the wil upon exit. Hence this is intended solely for better maintenance.

import os
import shutil
p = os.path.join(os.path.dirname(__file__), "shortcutsrc") 
shutil.copy(p, p + ".bak")                                 
lines = open(p).readlines()                                
idx = next((i for i, x in enumerate(lines) if "(file-version" in x), -1) + 1 
active, inactive = [], []
for x in lines[idx:]:                                      
    if not x.strip(): continue                             
    (active if x.strip().startswith("(action") else inactive).append(x) 
open(p, "w").writelines(lines[:idx] + ["\n# ACTIVE\n"] + active + ["\n# INACTIVE\n"] + inactive)

Below is a screenshot of the changes in a more readable format.

• On the left: the shortcutsrc file updated at commit ca9c6f2
• On the right: my proposal

Note on deviations:

Some shortcuts differ intentionally from the PDF to accommodate GIMP's workflow:

e.g. (action “tools-bucket-fill” “<Shift>g”)

In Photoshop, both the Gradient Tool and Paint Bucket share the G shortcut, and users cycle through the stack using Shift+G.
Since GIMP handles tool cycling differently, I mapped:

• G -> Gradient Tool
• Shift+G -> Bucket Fill

If you agree with adhering to these shortcuts, I plan to submit further adjustments in future PRs. I'm open to feedback if further changes are needed.
