Cross-version shortcut migration guide generator for photo editors

When a retoucher or photographer updates their software and finds their shortcuts have changed, their first instinct is to Google what changed — and they find forum threads from 2019, Reddit posts with partial lists, and Adobe help docs that describe the current defaults with no comparison to what existed before. There is no authoritative, version-specific diff that says 'here is every shortcut that changed between CC 2021 and CC 2022, with the old key, the new key, and a one-click way to remap it back.'

This gap exists because Adobe documents their software as it is, not as it was. Version comparison is inherently backward-looking, and Adobe's documentation team has no incentive to maintain a living changelog of input behavior — that would be an implicit admission that they broke things. The people who feel this pain most are experienced users who paid for years of muscle memory and now have to unlearn it, but they're diffuse and complain in forums rather than filing structured bug reports that would pressure Adobe to respond.

Users say things like 'They changed some of the keyboard shortcuts and it's hard to remember that they did change it' — the hardest part isn't the remapping itself, it's not knowing which keys changed. Right now the only way to figure it out is either to notice the breakage in the moment (mid-project, costly) or to manually compare two versions of Adobe's shortcut documentation that aren't structured for comparison.

A service that maintains a version-by-version changelog of keyboard shortcut changes — across Photoshop and Affinity Photo — and generates a personalized PDF or printable cheat sheet showing only the shortcuts that changed between whatever two versions a user specifies, is something studios and training departments would pay for once and use repeatedly. Training managers who onboard new retouchers would pay for this because 'having to relearn the interface whenever there's a major update' is not just an individual problem — it's a recurring onboarding and retraining cost every time the software updates.

What to build

Build a web tool that maintains a structured, version-tagged database of Photoshop and Affinity Photo keyboard shortcut changes, lets a user select two version numbers, and generates a printable PDF cheat sheet showing only the shortcuts that changed — with columns for old binding, new binding, and a 'restore to old' instruction for each.

Where to start

Launch with a single, well-documented version transition that caused the most complaints — CC 2018 to CC 2019 on Mac is cited explicitly in user complaints — and use that specific guide as the acquisition hook, since people are still Googling that exact transition years later.

The hard part

Building and maintaining the version-by-version shortcut changelog requires manually testing each software release or having contributors who do — there's no API or structured source of truth from Adobe, so data quality is entirely a human curation problem from day one.

How it makes money

Free for a single version comparison with watermark, $9 one-time for a clean printable PDF, and $49/year for training teams needing unlimited version comparisons and team-branded output.
