How to exit while loop with IRRemote library

I'm trying to write some code to control a WS2812B LED strip using an IR remote using the FastLED library. I'm able to control the fill_solid and BRIGHTNESS cases properly, but I'm having trouble with the 0xFFA25D ("CH-") case. I want it to be able to run continuously until another button is pressed, but I can't seem to get the IR receiver to read within the while loop.

#include <IRremote.h>
#include <FastLED.h>

#define LED_PIN     8
#define NUM_LEDS    55
#define LED_TYPE    WS2812B
#define COLOR_ORDER GRB
CRGB leds[NUM_LEDS];
int BRIGHTNESS = 55;

const int RECV_PIN = 7;
IRrecv irrecv(RECV_PIN);
decode_results results;
unsigned long key_value = 0;

CRGBPalette16 effects[4];

int count = 0;
int hold = 1;

void setup() {
  Serial.begin(9600);
  irrecv.enableIRIn();
  irrecv.blink13(true);

  FastLED.addLeds<LED_TYPE, LED_PIN, COLOR_ORDER>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
  FastLED.setBrightness(BRIGHTNESS);

  effects[0] = RainbowColors_p;
  effects[1] = RainbowStripeColors_p;
  effects[2] = CloudColors_p;
  effects[3] = PartyColors_p;
}

void loop() {
  if (irrecv.decode(&results)) {

    if (results.value == 0XFFFFFFFF)
      results.value = key_value;

    switch (results.value) {
      case 0xFFA25D:
        Serial.println("CH-");
        hold = 1;

        while (hold == 1) {
          static uint8_t startIndex = 0;
          startIndex = startIndex + 1; /* motion speed */

          FillLEDsFromPaletteColors(startIndex);
          FastLED.show();
          FastLED.delay(10);

          irrecv.resume();
          if (results.value != 0xFFA25D) {
            hold = 0;
          }
        }
        break;
      case 0xFF629D:
        Serial.println("CH");

        count++;
        break ;
      case 0xFFC23D:
        Serial.println(">|");
        break ;
      case 0xFFE01F:
        Serial.println("-");
        BRIGHTNESS -= 10;

        if (BRIGHTNESS < 0) {
          BRIGHTNESS = 0;
        }

        FastLED.setBrightness(BRIGHTNESS);
        FastLED.show();

        break ;
      case 0xFFA857:
        Serial.println("+");
        BRIGHTNESS += 10;

        if (BRIGHTNESS > 255) {

Thank you for any help!
