"Re-map" cmd+click to ctrl+click in specific app

Dear community,

Let me start off by mentioning how much in love I am with this software. I’ve built quite some triggers over the last couple of weeks and BetterTouchTool is making me love using my MacBook even more.

As my work requires me to RDP to a Windows jumpbox, and because I’m using Royal TSX software to do so, I’ve made a couple of app-specific triggers to re-map some keyboard shortcuts like CMD+C to CTRL+C. These are all working as expected.

My next objective is to “re-map” cmd+click to ctrl+click (or middle-mouse-click) to open hyperlinks within the RDP window as a new tab, but not shifting focus to said new tab. What I’ve tried so far with different outcomes:

All of the triggers below are per-app for Royal TSX, are all Trackpad gestures, and all have “trigger only while holding CMD” enabled in the Trackpad Gesture Configuration:

  • Trigger; 1 Finger FORCE click
    • Action; “Middle Click (At Current Mouse Position)
      • Result: this consistently works, but (as can be logically expected from the trigger criteria) it will only work when the trackpad is pushed hard enough to trigger the ‘force’ criteria. When not pushing hard enough, the trigger isn’t matched so the regular non-modified click happens (which feels like a wierd self-inflicted UX).
      • Note: I could probably solve my UX-issue if there were a ‘single finger click’ (non force) trigger (regardless of the corner, for which there are options) and duplicate those, but I’m assuming it isn’t included in BTT yet for a reason.
  • Trigger; 1 Finger tap
    • Action; “Middle Click (At Current Mouse Position)
      • Result: the tab opens in the background, but the ‘tap’ also causes the same link to be opened in the same tab. I haven’t been able to find an action that ‘cancels’ the original click from the trigger yet.
      • Note: if this would never work because there is no cancel-action, and the action needs the original click from the trigger to be executed, I could also live with an option that disables cmd+one-finger-tap completely and solely rely on the "cmd+one-finger-force-click” trigger.
    • Action; “Custom Mouse Buttons & Modifiers” (Custom Click: ctrl+left)
      • Result: seemingly at random, it either ignores “ctrl” and simply opens the hyperlink in the active browser tab, or opens the link in a background tab but also clicks the link causing it to also redirect in the active tab.
    • Action; “Custom Mouse Buttons & Modifiers” (Custom Click: middle)
      • Result: same as above
    • Action; “Modifier Keys → Ctrl key down”
      • Result: this causes the flow to work as expected, in the sense that tabs are always opened in a new tab and the current tab is unchanged. However, the modifier key remains “pressed” post-execution causing regular clicks to be executed as well. I’ve not found a “cancel / stop pressing the modifier key” yet.

Would love to get some insights / tips / ideas etc.
