 * SubGHz: KeeLoq **display BFT programming mode TX** (when arrow button is held)
+* SubGHz: KeeLoq **add counter mode 7 (sends 7 signals increasing counter with 0x3333 steps)** - may bypass counter on some receivers!
 * SubGHz: Add signals button editor and real **remote simulation** (full signal transmit with just one click) (PR #956 | by @Dmitry422)

 **Mode 6:**
 - Counter freeze - do not increment
 
+**Mode 7:**
+- Incremental mode: `+0x3333` 5 times to current counter and return original value back adding +1 - 2 times - 7 signals in pack total
+- Might work with Doorhan, seen in some "universal remotes"
+- One click of Send button on flipper may bypass receiver counter, wait for full transmission
